In the Church of Saints Peter and Paul the relics of St. John of Polivotsky were transferred to the church by Tsar Kaloyan in the capital city of Turnovo in 1204. Subsequently, a monastery complex was formed around the church. It was built according to the will and priesthood of Anna-Maria (1221–1237), wife of Tsar Ivan Assen II. During the Ottoman rule, hundreds of manuscripts from the royal library were placed there. Many of them were destroyed in 1842 by the Greek ruler.
The church is dedicated to the Christian Apostles Saint Peter and Saint Paul. It follows the cross-domed design and has a single apse. The cella is divided into three naves by two rows of columns. The columns' capitals are decorated with plastic carving and tracery. The church has a high, massive iconostasis. According to the 14th-century account of Patriarch Evtimiy, the church and the surrounding monastery were built on the order of Tsar Ivan Asen II's (ruled 1218–1241) wife Anna.
The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
