|The Charles Bridge in Prague, Czech Republic was built in 1342-1406 and represents one of the most famous mediaeval sites in the Central Europe (Figure 1). Below the water level, the pillars are made of granite blocks. Above the river, the masonry consists of various sandstones. During its history, the bridge was damaged by floods several times. After the floods, it was reconstructed by various methods. The original composition of the bridge flooring was substantially changed during the last reconstruction in 1976, when a reinforced concrete slab was embedded to the flooring and a granite pavement was laid on the concrete bed.
