Old caves found under park in St. Leonard

Quite a discovery under St. Leonard, in the east end. 

Some massive underground caves have been found under Parc Pie-XII stretching for about 200 meters. 

There are rock formations and waterways inside. 

The borough is looking at how it might open them up to the public without damaging them. 

Officials say they are 15 000 years old.
