Dating from the middle of the 16th century but now featuring mostly the combined Rococo design of Johann Christoph Glaubitz (Jonas Kristupas Glaubicas, c.1700-1767) and later Neo-Byzantine modifications, the entire ensemble is comprised of the church, a free-standing bell tower, monastery and convent. The church is positively bursting with frescos, icons, a magnificent cupola and rich blue and green colours. A particular quirk of the church’s crypt saw it being chosen in the middle of the 19th century as the final resting place of the supposedly incorruptible Saints Jonas, Eustachius, and Antanas, couriers of Algirdas whose remains are displayed dressed in white at Christmas, in black during Lent, in red on all other occasions with the exception of June 26 when they’re put on display entirely naked.
