The parish in Łososina Górna itself is much older than the present church. It was first mentioned in 1320. In 1543, the temple was taken over by Arians thanks to the then-owner of the estate, Andrzej Rupniewski.  The Catholics did not recover the destroyed and profaned church until 1615. The present wooden, Baroque-style church was built in a timber-frame construction with a tin roof surmounted by a square tower. In 1891, the church was enlarged by the addition of two chapels to the presbytery.

The interior is decorated with figural and ornamental polychrome. The vault of the presbytery shows the scene of the Assumption of the Blessed Virgin Mary, while the vault of the nave shows the Last Judgement and the Coronation of the Virgin Mary. The interior decoration and furnishings are primarily in the Rococo style. The main altar is adorned with an image of Our Lady and Child, which is overshadowed by a canvas All Saints Adoring the Holy Trinity. Also noteworthy are a stone baptistery from the 15th century and a Rococo pulpit from the second half of the 18th century.

The church is located on the Wooden Architecture Route (Link to the description of All Saints' Church Łososina Górna).
