A part of the ruin of the Igreja do Carmo (Church of the Carmelites) shows in the left hand picture. The church was built in the late 14th century. At some stage this was the biggest church in Lisbon, which says a lot. The view in the left hand picture is from the Rossio in the Baixa district, while the church ruins are against the hill in the Bairo Alto district.
The ruin is what is left of the church, after the 1755 earthquake that struck while the congregation was holding mass and the roof came down on them. The lower level Baixa district was flattened by the quake and what remained was flooded by a resulting tsunami. The devastation was enormous and the Baixa district got to be rebuilt according to a plan. No more winding streets, but square and rectangular city blocks.
Climbing up the Bairo Alto hill and on the other side of the church ruin, there is a small town square housing the Chafariz do Carmo, an 18th century fountain, with beautiful tourist girls gawking at it. (Second pic from the left). The building behind the fountain canopy, is what is left of the church after the quake and houses a museum. For some reason there is a military guard at the museum door.
The picture on the right is of a window frame in a wall that survived the earthquake back then.
