The aim of the paper is to present the results of archaeological, architectural-historical and geophysical investigations in relation to the dehumidification of masonry foundation of a national cultural monument Lutheran church in Nitrianska Streda (ÚZ PF 11276/0). The church is situated on the western edge of the lowland village of Nitrianska Streda, on the left Nitra river bank. The archaeological research conducted by Department of Archaeology in Nitra in 2010 brought to light late medieval and modern period pottery fragments and older architecture. For this reason architectural-historical survey of uncovered architecture followed the research. As the southern continuation of the three identified structures were with high probability completely destroyed by the church foundations and crypt, the expected results on the nature of the estate brought the geo-radar research in the northern neighbourhood of the church. Examined national cultural monument can be after results of the research extended to an archaeological site – extinguished late medieval castle. On this site was build the church in 1748 and in 1811 enriched by a tower. The castle is mentioned in written sources from the second half of the 14th century.
