Via Sancti Martin

In the second half of the 17th century, a new crypt and a chapel of Loreto were built on its northern side. In the 19th century it was rebuilt in neo-Gothic style. On the eastern wall of the sanctuary there is a window, probably original from the Romanesque period. Five red marble tombstones can be seen in the walls of the sanctuary. In the chapel of Loretto, an ornate urn preserves the heart of the first Charles Khuen-Héderváry. There is also an urn with carved snakes on a stylised Corinthian column. Next to it, in a niche covered with a coat of arms, are three large silver urns. Behind the chapel's table altar is a wooden grid reminiscent of the Greek Orthodox churches. Above its parapet are the imperial, royal and family coats of arms, decorated with Baroque ornaments. Behind the grille is a statue of the Virgin Mary carved in ebony. The Chapel Gallery hosts temporary exhibitions.
