Utterly arcane question about the Roman Forum

Factual Questions
1

This is for people who know the city of Rome very well. I’m
trying to remember the names of a couple of monuments I saw
in the Forum when I was there myself, years ago. They’ve both been converted into churches, and are on the same side
of the Via Sacra.

The first one is near the Curia and was a temple dedicated, I think, to Antoninus and Faustina, but is now a church.
The other one is further down the Via Sacra, moving toward the Colosseum, and was the Temple of Divus Romulus, and has
a working fourth-century bronze door opening on the Via Sacra (though it’s always locked as far as I know). Present day churchgoers and tourists enter on the other side of the
building, from the Via Dei Fori Imperiali.

What are the names of these churches?

The temple of Antoninus and Faustina is now the church of San Lorenzo.

The temple of Divus Romulus is part of the church of Santi Cosma e Damiano.

Uh, sorry. I thought I was somewhere else.
