The Frsk Letterkundich Museum (Frisian Literary Museum) is located on Grote Kerkstraat in Leeuwarden. The building that houses the museum was once the home of local heroine Mata Hari. The museum displays a large collection of Frisian documents, and a number of pamphlets in English detailing the Frisian language. There is also a permanent display relating to P.J. Troelstra, a Frisian socialist politician and poet.
