Sante Orsola e Catarina was a small church on the east side of what is now the Via del Teatro Marcellino, opposite the entrance to the convent of Tor de’ Specchi. This is in the rione Campitelli.
It was demolished in the 1930’s as part of a scheme to provide a trunk road from the centre of the city to the southern suburbs, which entailed the widening of what had been a rather narrow street. Most of the buildings on the east side, including this church, were removed.
