Nallin Farm Springhouse and Bank Barn
 The Nallin Farm Springhouse and Bank Barn are closely associated with the Nallin Farm House on the grounds of Fort Detrick Maryland. The barn is a good example of a fieldstone-built bank barn with a byre on the lower level and an earth ramp on the opposite side providing access to a haymow.The simple stone springhouse is the source of 3-1/2 acre Nallin Pond. The barn and springhouse were built circa 1800.
