The Stulpinai Chapel is a unique tourist attraction in the Telšiai district, Viešvėnai Eldership, near Degaičiai. This wooden chapel, known as the Stulpinai Mother of God – Descent of the Holy Spirit Chapel or the Mirror Chapel, stands out due to its remarkable interior detail. Inside the chapel, visitors can see hundreds of mirrors, most of which are antique and faded. In honor of this distinctive site, a nearby street in the village of Rainiai is named "Mirror Street."
The chapel was built at the end of the 18th century on the land of a nobleman named Fabricius. Fabricius, a Latin teacher at the Telšiai Gymnasium, contributed to the construction of the chapel alongside the nobleman Važinskas. In 2003, the chapel underwent major renovations, including re-cladding of the walls, foundation reinforcement, and roof restoration. In 2015, the chapel was repainted. A bell that
once hung in the tower was stolen around 2001.
The chapel is small in volume, rectangular in plan, with a three-sided apse and a sacristy attached to the eastern wall of the apse. Built on a stone foundation, the chapel has a gable roof, with a hipped roof over the apse, all covered with sheet metal. At the northwestern end of the roof stands a small square tower with a multi-sloped, metal-covered roof and a wrought iron cross. The windows are wooden, featuring colored glass inserts in the shape of diamonds, with interior shutters. The corners and window trims are decorated with ornate windboards.
Inside, the main altar is dedicated to the Blessed Virgin Mary, with 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.
