While not as famous as the Great Wall or the Forbidden City, Yonghe Temple is still a great place to check out. More popularly known as the Lama Temple (yes, Lama not Llama - there are no animals here unfortunately), the temple was used as a temple and monastery for Tibetan Buddhism. Today, as well as a tourist attraction, it is still a functioning temple.
This temple is also the site of a Guinness World record. It has a 26 meter tall Buddah statue.
While this temple is a lot like most others in China, It's still really cool to check out. It's definitly a great place to visit while you're in Beijing.
