Design of the church on Zelená hora hill near Zdár nad Sázavou and its vicinity constructed in Baroque style is unique. Therefore was the church written to the list of UNESCO. The architect of the church Santini – Aichl (1677-1723) belongs to the most famous Baroque artists in the Central European region. The complex was built during the extremely short time – two and half years (1719-1722) and it was several times burnt down and reconstructed again. The plasters were according to records repaired in 1828 and the cloister in 1829. The latest reconstruction before the Second World War was realized in 1937.

The Lednice castle was built before the year 1585 in Renaissance style on the place of Gothic fortress from 13th century. Architect J. B. Fischer from Erlach during the second half of 17^th century reconstructed it. The riding-school was preserved from these times. Architect J. Wingelmüler realized the latest reconstruction in the English neo-Gothic style. Facade plastic ornaments represent romanticism style.

Materials applied during the construction and reconstructions were various. Architects used the combination of natural and artificial materials. The necessity or intention of application of artificial materials, which imitate natural ones by architects, is discussable. Perhaps for financial costs were preferred artificial materials, which can be easily formed.

Special prepared sculptural stone was used during the construction of sculptural fountain ornaments in Valtice. It was constructed in the half of 18^th century.

The comparative samples of plasters and mortars were taken by conservators in Tuscania in 1999 (Tuscany region in Italy) (Tab. 3).
