One of the oldest scientific institutions in the nation, the Maryland Science Center has undergone quite a few changes since its inception in 1797. The most recent renovation in 2004 expanded the facility and added new exhibitions on all levels. In addition to the exhibits, the Science Center also houses a planetarium, observatory, and an IMAX theater.

Founded in 1959 after the District of Columbia made plans to abandon the streetcar services, the National Capital Trolley Museum opened a decade later to the public. The museum´s permanent exhibitions collect and preserve artifacts from the era of electrical street railways. Learn more about the history of this transportation and take your own streetcar ride when you visit.
