Free admission is granted to disabled visitors and one companion each with a valid ID.
The tour sites have a strict dress code. Women must wear long, loose clothing that covers their arms and legs, along with a headcover at all times. Men should ensure their shoulders and knees are covered. Failure to comply will result in entry refusal.
Visitors need to leave the venue after the tour, due to the limited size of the crypt.
Check the official website for the daily opening hours before your visit.
