The Series Historic Buildings in Transylvania, launched in 1993, presents the most precious examples of Transylvanian built heritage connected to the Hungarian culture, with the purpose of drawing the general public's attention on values, heritage and our responsibilities towards these. The publications of this series are recommended especially to those who at present own or use such values, but also to those who are interested in history, architecture and the Transylvanian art.

Number 18 of the Series Historic Buildings in Transylvania presents the Calvinist Church in Acâş. The village's name originates from the Benedictine monastery founded by the Ákos clan. Its present brick masonry church formed by a pair of western towers, a nave and two aisles and an apse, originally had a pair of eastern towers as well. Later the monastery ceased to function, and with the spread of the Reformation at the end of the 16^th century, the Romanesque church became a Calvinist one. The 18^th century wooden furniture painted with folkloric motifs enlivens the whitewashed church interior’s puritan aspect.
