Some of the museums and attractions in the country are free - the Art Gallery "Am Tunnel", Bank Museum, Post and Telecommunication Museum, etc. Museums that are part of the Museumsmile offer free admission on certain days. If you are in love of the architecture of old buildings and religious centres you should pay a visit to the Neumünster abbey and the St John’s church, don’t miss the Quirinus chapel and St Michael's Church. For an extra amount of fun, don’t miss the Summer in the City Festival which takes place from end of June until beginning of September.
