The church of San Giorgio in Velabro, which stands in what was once the Greek quarter of the city, was probably built during the 7th century. The portico and bell tower were added later.
The nave is lined with sixteen ancient columns of granite and pavonazetto. The fresco in the apse, the only painting in the church, depicts Christ with the Madonna and St George and St Peter and St Sebastian. At the base of the altar there is a niche. Through the grille is visible what purports to be the skull of St George.
On July 27th 1993, the portico was destroyed by a car bomb, which had been planted by the Mafia. Within four years it had been beautifully reconstructed.
