Swampoodle was a neighborhood in Washington, D.C. on the border of Northwest and Northeast in the second half of 19th and early 20th century.

[1] The origin of the name "Swampoodle" is believed to come from a newspaper reporter covering the ground-breaking of the Roman Catholic St. Aloysius Church in 1857, who referred to the land at the site at the intersection of North Capitol and I Street as containing numerous swamps and puddles that often occurred when Tiber Creek overflowed its banks.

In 1856, the first Government Printing Office building was built on the southeastern corner of Square 624 and the following year, H Street was grated and graveled between New Jersey Avenue and North Capitol.

[3] The neighborhood gained a reputation for being a lawless shantytown, where crime, prostitution, drunkenness were rife during and after the Civil War.

[3] Swampoodle Grounds, a stadium with a capacity of approximately 6,000, was the home of the Washington Statesmen baseball team from 1886 to 1889.

The McDowell and Sons plant, seen in the background of the ballpark photo behind right field, was listed in city directories as the corner of Massachusetts Avenue and North Capitol Street.

As part of the plan, the remainder of Tiber Creek was covered up in a tunnel and the low-lying land in the area was filed in.

[3] This major project physically divided the neighborhood and led to many of the 1,600 former residents moving to other parts of the city.

It was produced by Solas Nua with support from the Ireland-based Performance Corporation to help combat stereotypes about the Irish.

CHRS is proposing to expand the Capitol Hill Historic District[13] to include these blocks as part of their Beyond the Boundaries initiative.

The announcement was made on December 13, 2017 after an online survey was conducted asking the community to vote for one of three possible names, the other two options being Old City Corner and 3rd and L Park.

[15] A bill codifying the name was introduced on April 9, 2018, and sponsored by Council Member Charles Allen (D) and Chairman Phil Mendelson (D).

These picnics were apparently known as Swampoodle Walks probably due to the rough nature of the events and the fights.
