Saint Pantaleon
It is believed that the early Halychian architectural style, thoroughly permeated with Romanesque influences from the West, had been transferred further north-east. The builders of temples in Halych are believed to have also been responsible for the extant Pereslavl Cathedral and Church of Intercession upon Nerl. The foundations of the Assumption Cathedral (1157) are still to be seen. The only surviving medieval church is that of Saint Pantaleon, originally constructed at the turn of the 12th and 13th centuries, but significantly rebuilt in the 17th century and controversially reconstructed in the 1990s. The archaeological excavations (1989–2005 under direction of Yuri Lukomsky) at the terrains of Krylos and Halych continue.
