The mosques in Oman are places of worship and should be treated accordingly even if you are only visiting to look at the beautiful artwork and architecture. Oman is home to many beautiful mosques, and they allow non-Muslims in on tours in some of these places of worship. When entering make sure to take off your shoes, dress in a way that your shoulders and legs are covered. In the case of women, wear a shawl over your head. Do not make loud noises or let your kids run about shouting.
