With so many years of history, Beijing is full of religion. From Confucian temples to Buddhist ones, from Catholic to ancestral shrines, Muslim Mosques and Jewish synagogues are also available in the city, so Beijing literally has something for every practitioner.
Of course the most common religious sites revolve around past and present Chinese religions like Daoism, Buddhism and Confucianism, as well as ancestral shrines. The Temple of Heaven was where royalty of old used to sacrifice animals to Heaven. It is a massive complex complete with sacrificial arena, kitchen (leftover sacrifice, anyone?) and of course the pagoda temples.
Confucianism was extremely popular in bygone China, and many still follow the more religious aspects of this social organizational structure. The Confucian temple is a beautiful relic of art and religion and is well marked with English information.
Five pagodas and the Lama Temple are also great representations of past years in China, though the markings are less obvious at these and thus information more scarce.
Christianity has never been widely accepted in China, but missionaries did establish churches that survive to this day. The Catholic Cathedrals of St. Joseph and Nan Tang are two such examples.
