18th and 19th centuries Around 1795, blacksmith John Tennally opened a small tavern at the intersection of present-day Wisconsin Avenue and River Road, which were former
Native American footpaths. Around a dozen families soon moved to the area, forming a village called Tennallytown, the second oldest settlement in present-day Washington, D.C. The village became a
stagecoach stop for people traveling between
Georgetown and
Maryland. In the
1791 plan for the new federal
City of Washington, the village was included in the city's boundary. Due to its distance from the city center, Tenallytown would remain a small rural village in
Washington County for many years. The village's name gradually changed to the present spelling, Tenleytown. In 1805 present-day Wisconsin Avenue became a toll road and was later
macadamized in the late 1810s and early 1820s. The village continued to grow in the 1800s, with a church, school, houses, and other businesses built near the tavern. By the 1850s the stagecoach service had ended due to the
Baltimore and Ohio Railroad and the village was connected to rural communities to its east by a country lane that was called New Cut Road or Road from Turnpike to Broad Branch. During the
Civil War farmland in the surrounding area was seized by the federal government after the
Union Army was defeated at the
First Battle of Bull Run. The government built
Fort Reno, one of 68
fortifications built to defend the city, on the city's highest natural point of 409 feet (125 m). The people who lived in the remaining houses on Grant Road took notice and sought to protect their properties from demolition. Following a historic landmark designation process, the 4400 and 4500 blocks of Grant Road and its 13 remaining historic buildings were added to the
District of Columbia Inventory of Historic Sites on April 21, 2002, and listed on the
National Register of Historic Places on March 3, 2004. The Grant Road Historic District was the first historic district in the city to include just a single street. In 2017 a mural depicting some of Tenleytown's history and landmarks was painted on the side of 4425 Wisconsin Avenue NW. ==Architecture==
