The King Abdullah Mosque, dedicated by King Hussein's grandfather, can be seen from every point of the city. Big and bright, it can hold up to 7,000 worshipers. Beautiful from the outside, all white with blue domes, but on the inside it's very spartan. In addition to the objects for religious purposes, there's a huge chandelier, and an even bigger carpet that covers the entire floor. Non-Muslims are allowed to enter, even in the period of Ramadan, but you must remove your shoes before entering. If you're wearing shorts or a t-shirt, you will be given a robe at the entrance.
As we were walking through the souk in Amman we came across the Al-Husseiny Mosque, built by King Abdullah I (grandfather of the present ruler) in 1924. It was built on the foundations of another mosque dating back to 640 BC. We couldn't enter when we were there because it was closed for religious services.
