Monastery Table

We bought this table from the people who sold us our house. Unfortunately I did not ask for any details about the table, all we were told was that it is a table from a monastery. It has faint design around the edge of the table top,  and a faint cross in the center of the table. I am not sure what style of cross this is. I am interested in getting more information about it, and find out if it is even worth what  we paid for it.
