Savage et al (2003:457-458) report the following:

To the south of the previously excavated Byzantine church, we uncovered two rooms with walls surviving to a height of 2 m. Each room has a door opening onto the flat stone pavement that separates these rooms from the church. The mosaic floors are preserved along with the bases of archways for ceiling supports. Coins, architectural stratigraphy, and style of mosaic decoration all indicate contemporaneity between the sixth-century church and rooms. The rooms were modified during the Umayyad period when the mosaic floor was repaired with flat paving stones along the damaged edges and some walls were reconstructed with differently sized stones. Further modification and re-use occurred during the Ayyubid-Mamluk period when new walls were built directly on top of the mosaic floors. The mosaic floor of the east room is extensively dented by collapsed wall stones, which suggests that use ended with destruction caused by an earthquake.
