Fort Reno Park is a park in the Tenleytown neighborhood of Washington, D.C.. It is the highest point in the city, and was involved in the only Civil War battle to take place in the District of Columbia. The highpoint was resurveyed and a new USGS Benchmark was placed in 2007 at coordinates N 38.95198 and W 77.075922, a location open to the general public and outside the fenced area where the highpoint was previously believed to be. Fort Reno, at 409 feet, is actually lower than the top of the Washington Monument, which rises 555 feet from nearly sea level. However, the sandstone castle-like fort structure on top and highpoint antenna farm raise the height above that of the monument.
