I am not one of the "chosen", but some people, when they listen with the ears of their minds, can hear the walls speak. The architecture, the shadow, they both scream high gothic revealing a time in history when the structure was built. There is artwork that talks of different times and artists, there is damage that speaks of natural and manmade traumas, there probably are gravemarkers that let you knos about those who officiated here and of those who had enough money to buy there place on the wall or on the floor. There may be graffiti that let's you know about a secret romance between one João and one Ana in 1974.
Ana Carloto, you are gifted. You probably do understand the walls.
