Which religions have to take off their shoes when entering their place of worship?

Removing shoes before entering a house is usually a cultural rather than a religious tradition. It is common to many Eastern countries, as well as Scandinavia.

However, some religions require removing shoes before entering a house of worship or a temple. Muslims remove their shoes before entering a mosque, Hindus remove shoes before entering a temple, and Sikhs remove shoes before entering a gurudwara.
