Portsmouth Athenæum

A non-profit membership library, gallery, and museum, incorporated in 1817 and located in the heart of historic Portsmouth, New Hampshire.

Armsden Photographic Project

In 2018, the Athenaeum received the photographic collection of prolific photographer Douglas J. Armsden (1918-2009). This collection of mainly mid-20th century images of Portsmouth will nearly double the Athenaeum’s entire photograph collection. Find out how you can help preserve this important collection.

The Shaw Research Library & Randall Gallery are open to the public from 1 to 4 p.m. Tuesday thru Saturday. Masks are required during your visit.
