A tombstone recovered from Kodungallur was stored in this synagogue and is on display in the front yard, with an inscription of Sarah Bat Israel, dating from 1269, making it the second oldest Jewish epitaph found in India.

[2][3] The hillocks at Kottayil Kovilakam are unique as the site of a Hindu temple, a Syrian Christian church, a mosque and a restored Jewish synagogue,[4] all within 1 km (0.62 mi) of each other.

This tombstone with the inscription of "Sarah bat Israel" is the oldest Jewish epitaph found in India, dating to November 1269 (Kislev 1581 Seleucid era).

The Golden Sefer Torah Crown was gifted by the Maharaja of Travancore to the Chendamangalam Jews.

There is also an abandoned Jewish cemetery behind the mosque, approximately 400 km (250 mi)[clarification needed] from the synagogue, which has not been restored.
