Take a look inside the historic Linen Hall Library (linenhall.com; free), which was established in 1788 by members of the United Irishmen and moved to its current location in a former linen warehouse a decade later. It houses an important Irish, local studies and political collection, including most of what has been written about Northern Irish politics since the 1960s.
Open Monday to Friday, don't miss the Troubled Images exhibition, a collection of iconic political posters that tells the story of Northern Ireland's sectarian conflict and peace process in the late 20th century. These visual representations show how the political landscape and attitudes towards armed conflict evolved in the 1970s, '80s and '90s.
