Umm, a bit confusing Margret. Your last three posts are 1865, 1864, 1865 in that order. Are we on 1863? If so, then I'll post this:

LAZARETTO POINT LIGHT REPLICA, Baltimore, MD. The decision to build where the original was located (still marked on city maps, directly across the mouth of Baltimore Harbor from Fort McHenry, at Lazaretto Point) was made because the government already owned five acres of land that they had used for a smallpox hospital. The hospital no longer operated there. In 1836 a fire destroyed the old hospital and damaged the keeper’s house. A new keeper’s house was built that year using salvaged bricks from the old keeper’s quarters and the hospital. This new house was 20' x 35' and 2 stories tall. In the late 1850s the original 11 lamps and reflectors of the light were replaced with a 4th-order Fresnel lens with a fixed white light.
In 1863 the Lighthouse Board took over the entire site of the old hospital to use for a storage depot for buoys but, because of the war, the area was used as an ordinance depot for the next 3 years.
