The Feast of Saint Catherine of Siena is on April 29th.
Though she’s from Siena, she lived and died in Rome. Her tomb is located under the main altar in the basilica of Santa Maria sopra Minerva, just behind the Pantheon.
The tomb can be visited anytime the church is open.
However, on her feast day, the church opens the area below the altar so that you can venerate the actual tomb.
At 6:00 p.m. there is a beautiful solemn Mass to celebrate her feast day. Following the Mass, it is possible to venerate the tomb.
To see even more of Saint Catherine, head on over to Siena. Though she was buried in Rome, her spiritual director knew that Siena would want to have a part of her as well. He went to her tomb, and her head separated from her body, so he sent it to Siena. Her head, and a finger, are located in her home parish, San Domenico.
The town used to process her Holy Head through the streets. But after several failed attempts to steal it, they locked it away for good. Three different people hold three different keys to three different locks. All must be present to open the reliquary holding the head. Access to the locks is in a small chapel off the sacristy.
Since San Domenico doesn’t have her full body, they only have a four star rating on Trip Advisor.
