The original medieval furnishing have been preserved in the interior:
A stone baldaquin from 1493, probably from the workshop of Matěj Rejsek which originally covered the tomb of bishop Augustin Luciano of Mirandola.
The baldaquin’s floorplan is a square.
It consists of four medium-sized stone polychrome abutments, which are terminated by the so-called ogee arch.
These arches are complemented by corner decorative turrets and enriched with Gothic ornaments.
Statues are placed on each support, roughly in the second third.
The supports that carry the architrave culminate in finials.
From the eastern side, the baldaquin is decorated with paintings by Karel Škréta.

An altar with a central woodcut of Christ's baptism was made by the master from Danube area.

The baptistery of 1414 (the oldest and largest in Prague)
A stone pulpit in the nave
Two works of the so-called Týn Calvary Master from the 15th century that are very valuable: Madonna of the Týn and the Calvary sculpture at the ending of the north aisle.
