The ancestral house of late DMK chief M Karunanidhi's family at Thirukuvalai village near here has suffered damage in the 'Gaja' cyclone, officials said Tuesday.
A tree in front of the house got uprooted and fell on the house damaging the tiled roof and a name board, they said.
The house is being maintained as a memorial and a library.
The cyclone crossed the Tamil Nadu coast near Vedaranyam in neighbouring Nagapattinam district on November 16 causing extensive damage and claiming 46 lives.
