Here’s another one of those unplanned stops.
At the end of La Rambla is a sea port heading off to the Mediterranean Sea. And around that edge is the Basilica de Santa Maria Del Mar or the Santa Maria of the Sea Basilica. Our driver (a Polish fellow who married a Venezuelan and are both now living in Barcelona) dropped us off there.
It was hard to see how it looked on the outside as it was already dark when we got there, plus the street it was on was very narrow. But inside, it was just as grand and beautiful as the Barcelona Cathedral.
Props to our driver.
