The culture of Bahrain is part of the historical region of Eastern Arabia. Thus, Bahrain's culture is similar to that of its Arab neighbours in the Persian Gulf region. Bahrain is known for its cosmopolitanism, Bahraini citizens are very ethnically diverse. Though the state religion is Islam, the country is tolerant towards other religions: Catholic and Orthodox churches, Hindu temples as well as a (now-defunct) Jewish synagogue are present on the island.
