The Piran Branch of the Regional Archives Koper was established in 1974. The Piran archives keep the oldest documents dating from the mid-12th-century period of the Venetian Republic and the oldest fully-preserved Slovenian City Statute from 1307. In October 2009 the archives moved to new premises in the town centre. They provide space for exhibitions and a small reading room for the study of the archives. The archival documents can be viewed on request and it is recommendable to order materials preliminary by phone or online.
