The crypt at the historic St Michan's Church in Dublin will re-open next week after being vandalised earlier in the year.
Thieves broke into the church in February and desecrated several mummies, including the remains of an 800-year-old crusader and a 400-year-old nun.
Archdeacon David Pierpoint said a skull and bones have been recovered and restored and security has been increased:
"If you ask most Dublin people they would say I've always meant to go there but never actually went and i think this will now spur them on to come and visit.
"We're looking forward to Tuesday to have it reopened, as we were saying, they [the mummies] are now back resting in peace which is the most important part."
