The Lisbon Cathedral, often called Sé de Lisboa, is the oldest and most important church in the city. Dating back to 1147, it survived battles and the devastating earthquake in 1755.
The Se Cathedral supposedly was a mosque at one time until the crusaders took the city and turned it into a church. This is only an urban legend in Portugal, but it adds mystique to your visit in knowing it.
It’s a formidable-looking cathedral that is more comparable to a castle than a church with its battlemented bell towers and reinforced walls. The treasury within is quite the treat to see, with its art, icons and relics to appreciate.
