The two-storey building was built in two phases. With the sup¬port of János Podmaniczky II in 1769-1771 a one-storey school building with mixed technique walls (sandstone, brick) and straw roof was erected. The second storey was built onto these thick, 18th cent. walls in 1872. That was the time when this rectangular planned building got its Classicist character. Its entrance has got a segment arch and decorated with an ornamented upper part. Today this building houses the permanent exhibition of the Petőfi Museum: "The Valley of Galga".

Behind the main building an uncharacteristical row of houses were built in the last third of the 19th cent. Between 1992-1994 this building was widened and reconstructed. Now it hosts the storages of the museum, the offices of the specialists working here, the restorer workshop, library and council room.

The assemblage includes a drawing room built at the end of the last century. Today this is the Gallery renewed for temporary exhibitions. In the park we find a sculpture portrait of Sándor Petőfi by Ferenc Kovács, well dated from 1770 (it was transport¬ed here from the Prónay palace of Acsa to escape the destruction) and three grave stones: a Catholic, a Lutheran and a Jewish one - they symbolize the three religions of the town. Up to 1931 the Lutheran Gimnazium (high school) functioned in the building. Between 1835 and 1838 Sándor Petőfi, the famous Hungarian poet was studying here.

Petőfi (in those days still Petrovics) was taught by István Koren, whose name was closely connected with the flourishing period of Schola Latina. From 1931 until the nationalisation (1948) the building was used as the boy dormitory of the Lutherans, and then the new power formed flats for the needy in it. From 1958 we find here first the museum of the Aszód District, and later, following the formation of the Direction of the Museums of County Pest (1962) it became one of the regional museums of the organization. As such it collects the values of the Galga valley. Its territory involves 19 settlements from Acsa to Zsámbok. The collection of the museum includes archaeological, historical, ethnographic and fine art objects, and also a significant library and a photo archive. At the same time this is the centre of the protection of monuments and archaeological sites in the region and centre of communal cultural education. The museum is a professional supervisor of 6 village museums of the region: in Dany, Galgamácsa, Iklad, Tura, Verseg, Zsámbok.
