One of the most visited sites in Prague, the Charles Bridge (Karlův most), known as the Stone Bridge (Kamenný most) prior to 1870, connects the Old Town with the Lesser Town (Mala Strana) and Prague Castle. The foundation stone of the bridge was laid in 1357 and commissioned by the Czech King and Holy Roman Emperor, Charles IV. It is said that egg yolks were mixed into the mortar during construction of the bridge as a means of strengthening it.©
