Baltimore () is an independent city and the largest city in the state of Maryland in the United States. Baltimore is located in central Maryland at the head of the tidal portion of the Patapsco River, an arm of the Chesapeake Bay, and is approximately 40 miles (64 km) northeast of Washington D.C.. Founded in 1729, Baltimore is a major U.S. seaport and is situated closer to major Midwestern markets than any other major seaport on the East Coast. Baltimore's Inner Harbor has always remained a major asset, once the second leading port of entry for immigrants to the United States and a major manufacturing center. Today the harbor is home to Harborplace and the National Aquarium in Baltimore and is a successful example of Baltimore's ambitious efforts at renewal. Following the fall of many of its largest manufacturing industries, Baltimore has shifted primarily to a service sector-oriented economy, with the largest employer no longer Bethlehem Steel but Johns Hopkins University and Johns Hopkins Hospital. Despite some successful revitalization Baltimore is still posed with many big-city challenges such as concentrated poverty and crime, and inadequate public education.

As of 2007, the population of Baltimore City was 637,455.^[1] The Baltimore Metropolitan Area, which includes the city's surrounding suburbs, has approximately 2.6 million residents; the 20th largest in the country. Baltimore is also the largest city in the Baltimore-Washington Metropolitan Area of approximately 8.1 million residents. Because there is also a Baltimore County nearly surrounding (but not including) the city, it is sometimes referred to as Baltimore City when a clear distinction is desired.

The city is named after Lord Baltimore in the Irish House of Lords, the founding proprietor of the Maryland Colony. Baltimore himself took his title from a place named Baltimore in Ireland, which is an Anglicized form of the Irish language Baile an Tí Mhóir,^[2] meaning "Town of the Big House" and referring to the O'Driscoll castle that still dominates the town. The Irish-language name for Baltimore is that of the O'Driscoll castle, Dún na Séad ("Fort of the Jewels").

History

Baltimore played a key part in events leading to and including the American Revolution. City leaders such as Jonathan Plowman Jr. moved the city to join the resistance to British taxes and merchants signed agreements to not trade with Britain. After the war, the Town of Baltimore, nearby Jonestown, and an area known as Fells Point were incorporated as the City of Baltimore in 1797. The city remained a part of Baltimore County until 1851 when it was made an independent city.

The city was the site of the Battle of Baltimore during the War of 1812. After burning Washington, D.C., the British attacked Baltimore on the night of September 13, 1814. United States forces from Fort McHenry successfully defended the city's harbor from the British. Francis Scott Key, a Maryland lawyer, was held as a prisoner of war on a British ship near the fort, observed the bombardment. Key wrote "The Star-Spangled Banner", a poem recounting the attack. Key's poem was set to a 1780 tune by British composer John Stafford Smith, and the Star-Spangled Banner became the official National Anthem of the United States in 1931.

Following the Battle of Baltimore, the city's population grew rapidly. The construction of the Federally-funded National Road (presently U.S. Route 40) and the private Baltimore & Ohio Railroad (B&O) made Baltimore a major shipping and manufacturing center by linking the city with major markets in the Midwest. A distinctive local culture started to take shape, and unique skyline developed peppered with churches and monuments. On visit to the city in 1827, President John Quincy Adams purportedly nicknamed it "Monument City"?a moniker that remained popular for well over a century.

Maryland did not secede during the American Civil War, but remained a part of the United States. However, when Union soldiers marched through the city at the start of the war, Confederate sympathizers attacks the troops, which led to the Baltimore riot of 1861. Four soldiers and 12 civilians were killed during the riot, which caused Union troops to occupy Baltimore. Maryland came under direct federal administration — in part, to prevent the state from seceding — until the end of the war in April 1865.

Following an economic depression known as the Panic of 1873, the Baltimore & Ohio Railroad company attempted to reduce its workers wages, leading to the Great Railroad Strike of 1877. On July 20, Maryland Governor John Lee Carroll called up the 5th and 6th Regiments of the National Guard to end the strikes, which had disrupted train service at Cumberland in western Maryland. Citizens sympathetic to the railroad workers attacked the national guard troops as they marched from their armories in Baltimore to Camden Station. Soldiers from the 6th Regiment fired on the crowd, killing 10 and wounding 25. Rioters then damaged B&O trains and burned portions of the rail station. Order was restored in the city on July 21—22 when federal troops arrived to protect railroad property and end the strike.^[4]

The Baltimore riot of 1968 occurred following the assassination of Martin Luther King, Jr. in Memphis, Tennessee on April 4, 1968. Coinciding with riots in other cities, public order was not restored until April 12, 1968. The Baltimore riot cost the city of Baltimore an estimated $10 million (about $63 million in 2008). Maryland National Guard troops and 1,900 federal troops were ordered into the city. Lasting effects of the riot can be seen on the streets of North Avenue, Howard Street, and Pennsylvania Avenue where long stretches of the streets are remain barren.^[6]

During the 1970s, Baltimore's downtown area known as the Inner Harbor, had been neglected and was only occupied by a collection of abandoned warehouses. Efforts to redevelop the downtown area started with the construction of the Baltimore Convention Center, which opened 1979. Harborplace, an urban retail and restaurant complex opened on the waterfront in 1980, followed by the National Aquarium in Baltimore, Maryland's largest tourist destination, and the Baltimore Museum of Industry in 1981. In 1992, the Baltimore Orioles baseball team moved from Memorial Stadium to Oriole Park at Camden Yards, located downtown near the harbor. Six years later the Baltimore Ravens football team moved into M&T Bank Stadium next to Camden Yards. On January 17, 2007, Sheila Dixon became the first female Mayor of Baltimore.^[7]

Geography

City plan of Baltimore (1852) by Lucas, Fielding Jr. of Baltimore.

According to the U.S. Census Bureau, the city has a total area of 92.1 square miles (238.5 km²), of which, 80.8 square miles (209.3 km²) of it is land and 11.3 square miles (29.2 km²) of it is water. The total area is 12.24 percent water.

Climate

Baltimore lies within the humid subtropical climate zone (Cfa), according to the Köppen classification.

July is typically the hottest month of the year, with an average high temperature of 91 °F (32 °C) and an average low of 73 °F (22 °C).^[9] Summer is also a season of very high humidity in the Baltimore area, with afternoon thunderstorms occurring regularly. The record high for Baltimore is 108 °F (42 °C), set in 1985. January is the coldest month, with an average high of 44 °F (6 °C) and an average low of 29 °F (-1 °C).^[9] However, winter warm fronts can bring periods of springlike weather, and Arctic fronts can drop nighttime low temperatures into the teens. The record low temperature for Baltimore is -7 °F (-22 °C), set in 1934. Baltimore rarely experiences temperatures below or above . Due to an urban heat island effect in the city proper and a moderating effect of the Chesapeake Bay, the outlying, inland, and higher elevation parts of the Baltimore metro area are usually several degrees cooler than the city proper and the coastal towns.

As is typical in most East Coast cities, precipitation is generous, and very evenly spread throughout the year. Every month usually brings 3-4 inches of precipitation, averaging around annually. Spring, summer, and fall bring frequent showers and thunderstorms, with an average of 105 sunny days a year. Winter often brings lighter rain showers of longer duration, and generally less sunshine and more clouds. Snowfall can occur occasionally in the winter, with the average annual snowfall around 21 inches (53 cm). Baltimore averages only 2-3 snow events per year^[10] In the northern and western suburbs, the climate begins to transition to continental, and thus winter snowfall amounts are usually higher, with some towns annually receiving 24-36 inches (61-91 cm).^[11] Freezing rain and sleet occurs a few times each winter in Baltimore, as warm air over rides cold air at the upper levels of the atmosphere. The cold air gets trapped against the mountains to the west and the result is freezing rain and or sleet.

The city lies in between two peculiar physical features that protect it from extreme weather and account for the relatively tempered seasons. The Appalachian Mountains protect central Maryland from much of the harsh northern winds and accompanying lake effect weather that bring subfreezing temperatures and heavy snows to the Great Lakes region, and the Delmarva Peninsula protects Baltimore from many of the tropical storms that affect the immediate coast.

The average date of first freeze in Baltimore is November 13, and the average last freeze is April 2.^[12]

Architecture

Baltimore is the home of the National Aquarium, one of the world's largest.

The city has architecturally important buildings in a variety of styles. The Baltimore Basilica (1806-1821) is a neoclassical design by Benjamin Latrobe, and also the oldest Catholic Cathedral in the United States. In 1813 Robert Cary Long, Sr. built for Rembrandt Peale the first substantial structure in the United States designed expressly as a museum. Restored, it is now the Municipal Museum of Baltimore, or popularly the ?Peale Museum?. The McKim Free School founded and endowed by John McKim, although the building was erected by his son Isaac in 1822 after a design by William Howard and William Small. It reflects the popular interest in Greece when the nation was securing its independence, as well as a scholarly interest in recently published drawings of Athenian antiquities. The Phoenix Shot Tower (1828), at 215 feet (65.5 m) tall, was the tallest building in the United States until the time of the Civil war. It was constructed without the use of exterior scaffolding. The Sun Iron Building designed by R.C. Hatfield in 1851, was city?s first iron-front building and it was a model for a whole generation of downtown buildings. The Johns Hopkins Hospital, designed by Lt. Col. John S. Billings in 1876 was a considerable achievement for its day in functional arrangement and fire proofing.

I.M.Pei's World Trade Center (1977) is the tallest equilateral pentagonal building in the world at 405 feet (123.4 m) tall.

Future contributions to Baltimore's skyline include plans for a 717 foot (218.5 m) tall structure known as "10 Inner Harbor". The building was recently approved by Baltimore's design panel and will be completed around the year 2010. It will include luxury condominiums, a hotel, restaurants, and shopping centers. The Naing Corporation has approved a tower of 50-60 floors for the lot at 300 Pratt street, with the design currently being finalized. The Inner Harbor East area will see the addition of two new towers which have started construction: a 24-floor tower that will be the new world headquarters of Legg Mason, and a 44-floor Four Seasons Hotel complex.

The streets of Baltimore are organized in a grid pattern. The streets are lined with tens of thousands of brick and Formstone faced rowhouses. Many consider the rowhouse the architectural form most closely associated to the city. Some rowhouses are dated as far back as the 1790s.

Oriole Park at Camden Yards is considered by many to be the most beautiful baseball park in Major League Baseball, and has inspired many other cities to build their own versions of this Retro-Style Ballpark.

Camden Yards along with the National Aquarium have helped revive the Inner Harbor from what once was an industrial district full of dilapidated warehouses, into a bustling commercial district full of bars, restaurants and retail establishments.
