Kabul is a city that has been through a lot. It is a city where you can see women in burqas walking alongside men in jeans and T-shirts. It's a city where you can hear the call to prayer five times a day, and also the sound of gunfire. It's a city where you can find ancient mosques and bazaars next to modern high-rise buildings. It's been ruled by the British, the Russians, and the Taliban. It's been bombed and shelled. But it's also a city with a rich culture and a long history. The city is home to more than 4 million people, and it's a major center of trade and industry in Afghanistan. If you're visiting Kabul, be prepared for a lot of dust and noise. The city is full of traffic and there's not a lot of green space.
