The chapel of the port of Málaga sits right in the middle of a now busy tourist area. It’s flanked by expensive restaurants, with towering apartment blocks behind it for tourists.
A review on Google maps (and Tripadvisor) is enlightening.
This is the Chapel of the Port of Malaga. Erected as an oratory in 1531 further out in the port area, but moved closer inland, brick by brick in 1719 and inaugurated as a chapel a few years later. It was used to say mass for seamen who were often extremely religious due in part to their dangerous profession. It’s a very old building and when juxtaposed against the modernity of Malaga Port, seems oddly out of place, yet all the more beautiful. Not a must see, but worth a detour if in the port area.
I can’t comment on how accurate that review is, as I couldn’t find any “official” page about the chapel, at least in English.
