The construction of the original building started back in 1241. It collapsed after the 1755 Great Earthquake. All downtown Lisbon was destroyed not only by the earthquake but also by the tsunami that followed it, but the façade of the Royal Palace chapel was rescued and used in the reconstruction of this church, as we see it today (previous post). About two centuries later (1959) a great fire destroyed the interior and roof. Restoration took place (for years and years!). However, all the stonework has been left ruined and I think it looks fantastic like that.
