Golden Gate, Gothic entrance gate at St. Vitus Cathedral, Prague 1, Czech Republic

The Golden Gate is the south entrance to St. Vitus Cathedral, opening onto the third courtyard of Prague Castle. Its Gothic porch with three pointed arches and a central pillar was designed by Peter Parler, and the upper floor carries a glass mosaic of the Last Judgment on a gold background.

The gate was designed by Peter Parler in the 14th century as part of the cathedral construction and is a key work of early Gothic architecture. Its construction reflects the ambitious architectural goals pursued during that period of growth.

The gate's name comes from the golden background of the glass mosaic of the Last Judgment (1370–1372), which shows Charles IV and his fourth wife Elizabeth of Pomerania kneeling among Czech patrons. The entrance itself is normally closed by a grille bearing Jaroslav Horejc's bronze reliefs of the twelve months, made in the 1950s.

The entrance itself is not used and is closed on the outside by a grille bearing Jaroslav Horejc's bronze reliefs of the twelve months, added in the 1950s. Visitors view the gate and its mosaic from the third courtyard of Prague Castle; the chamber above, holding the Czech crown jewels, is reached by a staircase from St. Wenceslas Chapel and is not open to the public.

The entrance is normally closed by an iron grille bearing a cycle of bronze reliefs of the twelve months, made by Jaroslav Horejc in the 1950s. Above the mosaic, a chamber reached by a staircase from St Wenceslas Chapel holds the Czech crown jewels.
