You can find sgraffito on the walls of old buildings throughout the Czech Republic. It is a form of wall decoration created by applying two layers of plaster with different consistencies and colour and then the careful scraping away (the word comes from the Italian verb to scratch) of some of the top layer to reveal the other thus creating a design. The designs can be simple but effective, as in the video above, creating the impression of stonework and sometimes depth. My husband and I came upon these two men restoring a building next to the Romanesque church in Trebic and I took this short video.
But sgraffito can also be used to create complex pictures. Here are some from Litomysl and Prachatice:
In some cases colour is added, as here on a building in Prachatice.
