DANBURY, Conn. (AP) Fire officials have condemned the building housing the St. Nicholas Byzantine Church in Danbury following a weekend blaze that gutted the structure.

Investigators have not determined the cause of the fire, which broke out on Saturday afternoon.

The fire destroyed much of the contents of the building and collapsed part of the roof.

Church officials were able to save some chalices and vestments from the flames.

They say they also will be able to salvage the church's tabernacle, which contains the sacraments used during worship services, and a single stained-glass window.

The congregation held services Sunday across the street at the Amber Room Colonnade.
