Mount Clare, also known as Mount Clare Mansion and generally known today as the Mount Clare Museum House, is the oldest Colonial-era structure in the City of Baltimore, Maryland, U.S.A. The Georgian style of architecture plantation house exhibits a somewhat altered five-part plan. It was built on a Carroll family plantation beginning in 1763 by barrister Charles Carroll the Barrister, (1723–1783), a descendant of the last Gaelic Lords of Éile in Ireland and a distant relative of the much better-known Charles Carroll of Carrollton, (1737–1832), longest living signer of the Declaration of Independence and the richest man in America in his later years, also the layer of the First Stone of the new Baltimore and Ohio Railroad, just a short distance away in 1828. The City of Baltimore purchased a large portion of the former estate in 1890 as its third large landscaped park. Mount Clare has been maintained by the National Society of Colonial Dames in Maryland, the local chapter of The National Society of The Colonial Dames of America, since 1917. In 1970, it was added to the National Register of Historic Places and was designated a National Historic Landmark for its architecture.

Pennsylvania Railroad 4876 was a GG1-class electric locomotive built in January 1939 at the PRR's Altoona Works in Altoona, Pennsylvania, United States. It is best known for being involved in an accident on January 15, 1953, when the locomotive overran a buffer stop, crashed into the concourse of Union Station in Washington, D.C., and fell partway into the basement after the train's brakes failed. Due to the major crowds expected for the upcoming inauguration of Dwight D. Eisenhower, 4876 was lowered the rest of the way into the basement and a temporary floor was erected overhead. After the inauguration, the locomotive's frame and superstructure was essentially scrapped on site, with all the reusable components shipped back to Altoona, Pennsylvania, to reconstruct a replacement 4876, which operated for another 30 years.

Hollins Market is the name of the oldest existing public market building in the city of Baltimore, Maryland. It is a contributing property to the Union Square-Hollins Market Historic District. The market, located at 26 South Arlington Ave just west of downtown Baltimore, runs the length of the 1100 block of Hollins St between South Arlington and South Carrollton Avenues. In 1829 the city granted the petition of a piano manufacturer named Joseph Newman and his brother Elias Newman, who together in 1842 founded Newman & Bros., (of whose pianos two are in the inventory of the Smithsonian), to erect a market house at their own expense on land donated by banker George B. Dunbar. That structure blew down in a windstorm in 1838; the market was rebuilt and opened the following year. The market was expanded in 1864 through a $23,000 appropriation by the city to construct the Italianate addition. The market is 29,803 square feet (2,769 m2) The Hollins Market building is at the center of the Hollins Market neighborhood. It is the geographical heart of what many refer to as Sowebo, and on the Sunday of Memorial Day weekend, is the center of an arts festival called Sowebohemian Arts Festival. Hollins Market is open Tuesday through Thursday 7:00 a.m. to 6:00 p.m., Friday and Saturday from 6:00 a.m. to 6:00 p.m. It is closed on Sundays and Mondays. In the early 1900s, many other businesses flourished around the market on Hollins St and other adjacent streets, including Riggy's Bar, Zirclears Bakery, Santo's Barbershop, etc. Actually Santo Scalco thought that it was such a great location, that he moved his barbershop from across the street from the Whitehouse where he cut several Presidents hair to 1141 Hollins St., which was at Hollins St. and Carrollton Ave.The 1990 Barry Levinson film Avalon depicts Hollins Market in the mid-1900s.

Hollins Market is a neighborhood in the Sowebo area of Baltimore. It takes its name from the Hollins Market, the oldest public market building still in use in Baltimore City, which is located in the heart of the neighborhood. Like the adjacent neighborhood Pigtown, Hollins Market has long been considered one of Baltimore's most promising neighborhoods because of its proximity to University of Maryland, Baltimore Medical Center, the Interstate 95 business corridor, Camden Yards, Ravens Stadium, the Inner Harbor, and Downtown Baltimore. Major construction projects such as the University of Maryland Biopark and the pending renovation of the Lion Bros. factory have brought increased attention to the neighborhood.Similar to Pigtown, Hollins Market has a diverse mix of UMMC students, blue collar workers, artists, and commuters to Fort George G. Meade. Hollins Market is also home to the Sowebo Arts and Music Festival which draws hundreds of art and music lovers to the neighborhood every Memorial Day Weekend.

The H. L. Mencken House was the home of Baltimore Sun journalist and author Henry Louis Mencken, who lived here from 1883 until his death in 1956. The Italianate brick row house at 1524 Hollins Street in Baltimore was designated a National Historic Landmark in 1985. Mencken wrote of his home: "I have lived in one house in Baltimore for nearly 45 years. It has changed in that time, as I have—but somehow it still remains the same.... It is as much a part of me as my two hands. If I had to leave it I'd be as certainly crippled as if I lost a leg."After his death on January 26, 1956, his home was bequeathed to the University of Maryland. In 1983 the City of Baltimore acquired the H. L. Mencken House from the university, in exchange for the Old Pine Street Station. With period furniture, his restored second-floor office, and backyard gazebo, the H. L. Mencken House opened as part of the City Life Museums and a center for theatrical, literary and musical events. Although the City Life Museums closed in 1997, the landmark still displays a special commemorative plaque about its famous occupant. The organization "Friends of the H. L. Mencken House" led efforts of several groups to redirect and expand the use of it. A $3 million donation from retired naval commander Max Hency in 2018 allowed the organization to begin renovating the house, and it opened to the public in 2019, though only by prior reservation.It was declared a National Historic Landmark in 1983.

Equitable Gas Works is a historic gas works located at Baltimore, Maryland, United States. It is a U-shaped complex occupying an entire city block and consisting of five 1882-1883 Romanesque Revival painted brick buildings ranging from one to two stories in height and one 1947 office building adjacent to CSX tracks in Spring Gardens, an industrial precinct in South Baltimore, Maryland. The rectangular, 19 century buildings are set on semi-coursed stone foundations, and are topped with monitor and gable roofs. The buildings exhibit a recessed wall plane behind paired brick pilasters and corbelled brick cornices and oculus openings set within their gables. The Office is notable for its delicate wood louvered dormer with a sunburst- ornamented tympanum. The exposed structural system remains visible in the industrial buildings; historic finishes also survive in the office building. The architect for the building is not presently known. The period of gas production in the complex extends from 1882 to 1901, when gas-related uses abandoned the site. Despite infill and alterations, Equitable Gas Works complex retains all of its original brick buildings and remains clearly recognizable as a purpose-built, 19 century gas manufactory. Both the form and massing of the buildings and the quality and character of surviving architectural fabric provide important evidence of the stature of the manufactured gas industry in the late 19 century. Equitable Gas Works was listed on the National Register of Historic Places in 2003.
