this dove did the catwalk in Prague on the Charles Bridge, a stone Gothic bridge that connects the Old Town and Malá Strana. Its construction was commissioned by Czech king and Holy Roman Emperor Charles IV and began in 1357. In charge of the construction was architect Petr Parlé? who did also build the Prague Castle. It is said that egg yolks were mixed into the mortar to strengthen the construction of the bridge. Probably the reason why birds like it.
