Pulpit Rock MR was a military reservation for the Harbor Defenses of Portsmouth. The site included an eight story Fire control Tower. A steel Fire Control Tower and AMTB Battery 951.

Eight Story FCT

In 1942 construction started on an eight story Fire Control Tower for Fort Dearborn nearby. The seventh story level DPF was designated for Battery 103/Seamen and the eight level DPF was for Battery 204. The roof was used as an Anti Aircraft Spotting station. The tower was completed in 1943 on a government owned .44 acre tract. The navy had control over the tower from 1954-1971. The fish and game department has owned the tower since 1974. It was suggested for the national register of historic Places in the 1970s but was not accepted and finally made the list in 2010 after being on the seven to save list in New Hampshire. In 2008 the Friends of Pulpit Rock Tower was formed to preserve the tower. The tower officially opened in 2009 on some holidays and continues to do so. The tower has been under restoration for many years and is still as of 2022.

Steel FCT

In 1942 on a separate tract of land a steel FCT was built near the main tower and used for Battery 205 and the Harbor Defenses of Portsmouth. This tower was dismantled around 1953.
