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 34 of the Series Historic Buildings in Transylvania presents the Haller Manor House in Sânpaul, the earliest dated settlement of the region (1332). In 1609, Prince Gábor Báthory donated the village to István Haller, who in 1610 built a castle here with a quadrilateral layout, the corners of which were protected by bastions. It received its current U-shaped layout between 1772 and 1778, when Gábor Haller, being in connection with the Grassalkovich family, reconstructed it following the model of the Manor House in Gödöllő (Hungary). The entry of the Russian army in 1945 affected the building gravely; the Haller family, deported in 1949, used only its ground floor. Due to the nationalisation and negligence, the castle became unusable by the end of the 20^th century.
