The Old Town Bridge Tower serves as the gateway between the Charles Bridge and Prague's Old Town district. It is considered the most beautiful bridge tower in Europe.

The
Old Town Bridge Tower was designed by Peter Parler,
the architect of the
Charles
Bridge, as part of the fortification system around
the Old Town.
The Late Gothic Tower, known as the most
beautiful bridge tower in Europe, was built between
1370 and 1391 at the Old Town side of the Charles Bridge
and served as a gateway to Prague's city center.
The 64m tall tower was richly decorated
on both the east and west facade, but the sculptures
on the west facade (towards the Charles Bridge) were
severely damaged during a siege by Swedish troops in
1648 and removed afterwards. Fortunately,

the decorations on the east facade were preserved.
Above the arch are the coat of arms of all the lands
that were part of the Bohemian Kingdom as well as the
kingfisher, the symbol of King Wenceslas IV.
The three
statues above the coat of arms depict the patron saint
of Bohemia, Saint Vitus in the center with King Charles
IV to his left and King Wenceslas IV to his right. Near
the top of the tower are two statues of Saint Sigismund
and Saint Vojtech (Adalbert).
A long stairway leads to an observation
room from where you have great views of Old Town and
the Charles Bridge.
