Degučiai St. Vincentas Fereras’s Church is the only remaining triangular wooden church in Europe. A triangular building plan of the church is very unusual and is associated with a symbol of the Holy Trinity. A baroque Degučiai Church was built in 1760. It was built by Vainutas Elder Tadas Bilevičius. It is believed that the construction of the church may have been induced by “a dark spot of the family”: from the historical sources it is known that a tragedy struck the Bilevičiai family when Aleksandras Bilevičius attacked his brother Vainutas Elder Jonas’s estate and Jonas’s wife Joana was killed during the attack. Thus Aleksandras Bilevičius may have started and his son Tadas Bilevičius completed the construction and equipped the church.
