Monastery Na Zderaze, Medieval monastery in New Town, Czech Republic.

Monastery Na Zderaze was a provostry of the Knights of the Cross with the Red Cross, canons following the Rule of Saint Augustine, in Prague's New Town. Of the whole complex only two structures survive: the Baroque former provostry building at Na Zderaze 269/4, now used by the Czech Technical University, and the small Chapel of the Holy Sepulchre with blind pointed arches in its chancel, standing in the courtyard at Na Zbořenci 276/II. The church of Saints Peter and Paul no longer exists.

The monastery was founded around 1190 and operated under the Canons Regular order, becoming an important religious establishment in medieval Prague. It was destroyed during the Hussite wars in the 15th century and never fully recovered its original religious role afterward.

The name Zderaz comes from the royal retainer Zderad, first mentioned in 1090. The monastery belonged to the Knights of the Holy Sepulchre, canons following the Rule of St Augustine, and its provostry was restored in 1440 after the Hussite wars but housed only two religious. In 1784 Joseph II abolished the canonry.

The monastery is located in Prague's New Town and can be viewed from outside, as parts of it are incorporated into residential buildings. Visitors should note that the grounds are not freely accessible, so it is best to observe the visible remains from the street.

The chapel of the Holy Sepulchre, the only part of the monastery still standing, has blind pointed arches in its chancel and stands inside the courtyard at Na Zbořenci 276/II. It has been listed as a cultural monument since 22 December 1964, while the whole complex was protected from 3 May 1958 under number 40111/1-1228.
