Annexed to the lovely Campo Maior Mother Church, this is the second largest bone chapel in the Country (the biggest one is located in the famous São Francisco Church, in Évora).

Dated from 1766 the Chapel was built after the huge explosion on a powder magazine back in 1732 which destroyed much of the city and caused around one thousand deceases.

The Chapel’s interior is totally covered with the victim’s bones of this tragedy. The floor pavement dates already from the 20th century.
