Sanctuaries were managed by a convent of women who cared for the lost and injured.
There are four Sanctuaries.
The size of the sanctuaries, however, was compensated for by their number; in Ostia alone there were five.
They served the threefold purpose of sanctuaries, reservoirs and assembly-rooms. A special feature was their use for the celebration of marriages.
With the definite triumph of the church, the profanation of its sanctuaries became less frequent, and once robbery or seizure of ecclesiastical possessions or violation of its privileges tended to absorb the attention of synods and popes.
