The architecture of the Church St. Gaspare del Bufalo has a pyramidal shape and almost on its top there is an oval-shaped glass window that seems an eye; both shapes recur often in Masonry. In addition, we can notice some unusual symbols for Christianity inside also: a 5-pointed star, a Cross of Lorraine (emblem of Dukes d'Angiò, considered as the descendants of Christ by some people) and a spiral who recalls the DNA one.
