What can arguably be considered to be Tallinn's main attractions are located in the old town of Tallinn (divided into a "lower town" and Toompea hill) which is easily explored on foot. The eastern parts of the city, notably Pirita (with Pirita Convent) and Kadriorg (with Kadriorg Palace) districts, are also popular destinations, and the Estonian Open Air Museum in Rocca al Mare, west of the city, preserves aspects of Estonian rural culture and architecture.
