What religion is Meteora?

Excuse me, could you clarify what you mean by asking "What religion is Meteora?"? As I understand, Meteora is a mountainous region in Greece, known for its stunning natural beauty and its monasteries perched precariously on the cliffs. It is not a religion itself, but rather a place where people of various faiths, primarily Orthodox Christians, have sought spiritual solace for centuries. Are you perhaps asking about the religious affiliation of the monasteries in Meteora? If so, they are primarily Orthodox Christian monasteries.
