Just to the right of the Basilica del Santo is the tiny church of San Pietro. In San Marinese terms it's the spring chicken of churches, having only been built at the beginning of the 19th century. As late as 1914, a crypt was built underneath the church to conserve the urn in which the bones of the Saint are resting.
The church's impressive staircase has been carved out of the bell tower of the high basilica.
