Archaeological Survey of India has declared this cave as centrally protected monument.

The grove spread over in 3.5 acres is jammed with 110 critically endangered tree species known as Kulavetti or Vathamkollin in local language and Syzygium travancoricum scientifically which is included in the IUCN Red list.

There is a natural cave in the Kalasamala hill-top dating back to the Stone Age which is known as Narimada (the abode of Tiger).

Kalasamala has now become a tourist destination and cinema shooting place as it offers nature in its totality.

Fr Augustine John Ukken was the parish priest here from 1928 till 1953, with a brief gap of 2 years.
