Charles Bridge

Construction of the Charles Bridge (Karlův most) began in 1357, after its predecessor, the Judith Bridge, built around 1160, was destroyed in a flood in 1342. Its original name was simply "Stone Bridge" (Kamenný most) or "Prague Bridge" (Pražský most).
It has only been called Charles Bridge since 1870. It stands on 16 pillars and is 516 meters long. Above the first pillar on the Old Town side rises a gate tower, considered one of the most beautiful Gothic towers in existence. The other 15 pillars are decorated with sculptures on each side. But this wasn't the case from the beginning:
the sculptures were only added after 1700.
At the bridgehead on the Lesser Town side, there are two towers, the smaller of which is said to have originated from the Judith Bridge. The larger tower houses a tourist information office, and like the Old Town Bridge Tower, it can also be climbed.
Like the Old Town Bridge Tower, it is open daily.
Both towers are open daily from 10 a.m., until 7 p.m. in winter and until 10 p.m. in summer. Admission is 75 CZK each.
The Charles Bridge is a pedestrian-only bridge and one of the most popular tourist destinations. Among the almost constant stream of visitors, there are
occasionally souvenir vendors. Very often, these are painters who market their artistic creations here. And it is probably also one of the places where one can expect an increased incidence of

The walk across the Charles Bridge is often accompanied by music from street musicians. But there are also some artists who sell their pictures and engravings with motifs from Prague, for example, or you can also have a portrait painted of you.Where there are so many tourists at once and it is so narrow, pickpockets are of course not far away. Just be careful and carry your backpack forward if necessary.

As a person who lives now for some time in the city I can only recommend in the morning very early if you want to see everything in peace.
