Backroads: Dalmatian Coast. Architecture

I loved the architectural details I saw in Dubrovnik.  There were clearly some Venetian influences, and the red rooftops instantly signify Dubrovnik.  Not sure what influenced the dome below, does anyone know?

The first one below is Sponza Palace.  I am not sure what the second one is, but I was standing in the same spot.  Perhaps part of Church of St. Blaise?

Finally, another view of the rooftops.  Air conditioning units, satellite dishes, attic dormer windows, laundry flapping in the breeze...  some things old, some things new.
