Mass Rock

Long ago there were Penal Laws in Ireland. These laws 
 ordered priests and bishops to leave the country so there
 could be no Mass for the Catholics. 
But, many priests stayed in the country and hid in the woods. All the Catholics would come to a hollow place and priests said Mass, usually at a big rock that was used as an altar. This was called a Mass Rock. 
There is a Mass Rock near our school.
 It is in Chapel Hallow. It reminds us of the hard times
 Catholics had in Ireland keeping their faith in God.
