After 1948 the fields were collectivised and the manor was nationalised. Between 1964 and 1970 it was thoroughly restored and handed over as a residence for artists, and international sculpture symposia were held in its park — sculptors came from abroad, worked on the spot and left their pieces standing among the trees, which is why a village park in the Považie is hung with modern sculpture. In 1976 the neighbouring villages of Ducové and Hubina were joined to Moravany, so that for sixteen years the Great Moravian court at Kostolec lay inside this village's boundaries.Po roku 1948 polia združstevnili a kaštieľ znárodnili. V rokoch 1964 až 1970 ho dôkladne obnovili a odovzdali ako sídlo pre výtvarníkov; v jeho parku sa konali medzinárodné sochárske sympóziá — sochári prichádzali zo zahraničia, pracovali priamo na mieste a diela nechávali stáť medzi stromami. Preto je dedinský park na Považí ovešaný modernými sochami. Roku 1976 k Moravanom pripojili susedné obce Ducové a Hubinu, takže veľkomoravský dvorec na Kostolci strávil šestnásť rokov v chotári tejto obce.
