Lisbon is a census-designated place located in western Howard County in the state of Maryland, United States, located roughly between Baltimore and Frederick and north of Washington, D.C.[2] It is contained in an area of roughly one square mile. Lisbon is located along Interstate 70 and Maryland Route 144 and is home to the first roundabout in Maryland (opened in 1993).[3] [4] It first appeared as a CDP in the 2020 Census with a population of 282.[5]
Lisbon is situated on a land grant patented by Seth Warfield in 1794 as "Warfield's Forest". The town was founded by Caleb Pancoast in 1810.[6] Named "New Lisbon", followed by a shortened "Lisbon" name (not Portugal's capital).[7] In 1820, Pancoast deeded land for the Union Church for Public Worship which would become a schoolhouse with gravesites remaining in 1880. Pancoast subdivided the town in 1822 with one hundred lots of a quarter acre in size, including roads and alleys. By 1835, eight scheduled daily stagecoaches ran through town.[8] The town built the single room Annapolis Rock School in 1894, which served the area until 1943.[9]
The photograph is the National Road (now MD 144), looking east toward Baltimore. The road between the two houses is Madison Street. Through the center of town, Woodbine Road runs north for 2miles to Woodbine, where the Patapsco River and the B&O Railroad cross the road. About one mile north of Lisbon exists the original road that ran from Baltimore to Frederick. This road runs west toward Poplar Springs and east toward Sykesville. The exact route of this road is not discernible at this time.
Lisbon is home to the Carr's Mill Landfill, the county's second landfill, which closed in 1977 and was the site of toxic dumping.[10]
Lisbon changed from an unincorporated community to a census-designated place for the 2020 census.[11]
