An expensive hour-long taxi ride later and I'm dropped off nearby and have to walk for 20 minutes to find the mosque. As I round the corner I see cars, motorbikes and scooters scattered around its outskirts. It's prayer time and if the rows of shoes are any clue to the number of people inside, this is the busiest prayer time of the week. As I look up to the second floor of the outer mosque I can see hundreds of men squashed against the walls.
Despite catering to up to 15,000 people, the mosque is immaculate. It has a 73m-high minaret and a concrete main roof in the shape of a 16-pointed star. It's pristine, peaceful and calming.
The main roof covers the complex like an open umbrella. The floors are white - in fact there is a lot of white with the occasional splash of bright blue. Fountains and waterways create a serene atmosphere. After prayer time non-Muslim tourists are given bright purple gowns and a headscarf to wear while they trot around. Even if you do stand out a bit and the outfits look a bit Obi-wan Kenobi, the experience is worthwhile.
Nearby is the Islamic arts museum. The architecture alone is well worth the entrance fee. The four floors are whitewashed with glass-sided inverted domes through which light pours, illuminating ancient scrolls and manuscripts, embroidery, weapons and mini models of mosques from around the world.
How Islam has manifested itself in Malaysia is illustrated through batik cloth, textiles, jewellery and ceramics. The museum also has a section of Islamic artefacts from other countries.
But KL is not just about Muslim culture; other cultures coexist here. In a limestone hill on the outskirts of the city, the Batu Caves are a triumph of Hinduism. This is the most popular Hindu shrine outside India. I walked up 272 steps beside a 42.7-metre gold statue of Lord Murugan. It took 300 litres of gold paint from Thailand to cover the immense structure.
I clutch my camera and iPhone close, keeping a keen eye on the monkeys that sit on the railings. They are crafty and fast - tourists are warned not to have anything food-related on them and to watch their belongings.
