Pulpit Rock Tower
United States
The 186th tallest tower in the world
Pulpit Rock Tower, also known as Pulpit Rock Base-End Station (N. 142), is a historic military observation tower at 9 Davis Road in Rye, New Hampshire. Built in 1943 as part of the Harbor Defenses of Portsmouth, a series of military defenses around Portsmouth, it is the only one of fourteen World War II-era observation posts to survive. Now owned by the state, it is periodically open to the public, and maintained by a local non-profit organization. It was listed on the National Register of Historic Places in 2010.
