Selangor is a state on the west coast of Peninsular Malaysia, encircling the capital Kuala Lumpur. In the state capital, Shah Alam, the Sultan Salahuddin Abdul Aziz Mosque has 4 soaring minarets and a huge blue dome. To the northeast are the limestone Batu Caves, which house ornately decorated Hindu shrines. A large golden statue of the Hindu god Lord Murugan stands at the entrance, and monkeys scamper about.
