Old Town of Warsaw is ringed by sections of old defensive city walls. It is pretty big portion as for the European capital. Construction of the walls began in the first half of the 14^th century. Works were continued until the mid-16^th century. It is possible to walk along the walls through the special trail running between the inner and outer lines. In the outer circle of walls there is a famous monument to the Little Insurgent.

It was founded for the Augustinian Order in 1354 and destroyed during World War 2 in 1944. Only a partially burned crucifix survived which is now located in the central nave. Interior was minutely restored to a design by Sister Alma Skrzydlewska and the crucifix incorporated into modern design.

Next to the Cathedral is the Jesuit Church of the Virgin Mary of Grace founded by King Zygmunt III. It was built for the Jesuit Order between 1609 and 1629, at the same time as the monastery. This Mannerist-Baroque church dedicated to the Merciful Mother of God survived almost untouched until 1944 when it was destroyed.

St John’s Cathedral is the oldest church in Warsaw, built at the turn of the 14^th century and reconstructed in the Gothic style. Two coronations of Polish Kings took place here: of Stanislaw Leszczynski in 1704 and Stanislaw August Poniatowski in 1764.

The decision to build the Royal Castle was made when Zygmunt III Vasa moved the capital from Krakow to Warsaw in 1596. Castle was completely destroyed by the Germans during World War 2 and reconstructed from 1971 to 1988 thanks to efforts of the whole community.

The first part of Castle Square was in existence in 1644 but completed at the beginning of 19^th century. After the World War 2, the burger’s townhouses were restored which today surround the Castle Square. In the middle of the square stands the oldest secular statue in Warsaw – Zygmunt’s Column.

Old Town Square is a rectangular square of 90m by 73m and existed on the site of modern Market Square on the turn of the 13^th and 14^th centuries. Until the beginning of the 19^th century it was an administrative and commercial hub of the city.

The Old Town history goes back to the late 13^th . Today's look is due to complete reconstruction (1949 – 1963) after it was destroyed during World War 2. It is the oldest quarter of Warsaw and has a preserved medieval street plan.
