Stulpinai, a small village in the Viešvėnai Eldership of the Telšiai district, near Degaičiai, is known for its unique chapel. This chapel, officially called the Chapel of Our Lady – Descent of the Holy Spirit or the Mirror Chapel, stands out for its extraordinary interior. The chapel houses hundreds of mirrors, some of which are antique, cracked, and faded. In honor of this unique feature, a nearby street in the Rainiai settlement has been named "Mirror Street."
The chapel was built at the end of the 18th century on the land of nobleman Fabricius. Fabricius, a Latin teacher at the Telšiai Gymnasium, helped build the chapel along with another nobleman, Važinskas. In 2003, the chapel underwent extensive renovation, including cladding of the walls, foundation reinforcement, and roof restoration. The chapel was repainted in 2015. A bell that used to hang in the roof turret was stolen around 2001.
The
chapel is small in volume, rectangular in plan, with a three-sided apse. On the eastern wall of the apse, there is an added extension – a sacristy. The wooden chapel is built on a stone foundation. Its roof has a gable shape, with a hipped roof over the apse, all covered with sheet metal. At the northwest end of the roof, there is a small square turret with a multi-sloped, sheet-metal-covered roof topped with a wrought iron cross. The chapel’s windows are made of wood, with diamond-shaped colored glass inserts and interior shutters. The corners and window trims are decorated with ornate windboards.
Inside, the main altar is dedicated to the Blessed Virgin Mary, featuring a painting of "Our Lady of Mount Carmel," an altar table (mensa) with an antependium, a wooden statue of the Merciful Virgin Mary, and a wooden presbytery railing with balusters. A small bell hangs in the sacristy.
