There are several major temple complexes on the outskirts of the city, the most important of which is the Buddhist temple of Swayambhu. (It's referred to as the monkey temple by tourists for obvious reasons). The temple sits atop the highest hill in Kathmandu, so you get great, though very smoggy, views of the city as an added bonus. The temple is reached via a very long staircase up the hill. It's been a place of worship for 2000 years, so lots of smaller temples and memorials have grown around it, but pictured here is the main stupa. The somewhat creepy eyes are a manifestation of the all knowing Buddha, and are an easy way to identify Nepalese temples.
