The medieval church, built in honour of St. Martin the Confessor, was built jointly by the villages of Small and Big Pose in the 14th century. According to a document from 1400, the eastern window of the church's sanctuary marked the exact border between the two villages.
At the turn of the 20th century the parish church fell into disrepair, so Prince Miklós Esterházy had it demolished and rebuilt in 1905. According to the description of the parish priest at the time, József Wallner, the plans for rebuilding the 'ramshackle building' from the foundations were drawn up by the Viennese architect Ludwig Schone in a neo-Gothic style similar to that of the Church of the Sacred Heart of Jesus in Kőszeg. Some of the stone carvings of this old church are also found in the new church. The stained-glass windows of the new church, depicting St. Martin, were made thanks to a donation by Dénes Szluha Szluha of Verbo. The painting of the nave, which depicts the scene of the sharing of the cloak of Amiens, was made in 1882 by the Austrian painter Josef Veiter. The 1834 seal of the parish of Nagypöse also depicts the scene of the sharing of cloaks: Martin on horseback offers half his cloak to the beggar on the ground. The building is a monument
