Danang hosts a small enclave of the Cao Dai sect, a contemporary Vietnamese denomination incorporating aspects of all religions, including science. Most practitioners of Cao Daism are in the far south, but this Cao Dai temple is one of the largest outside of Tay Ninh, home of the Cao Dai Holy See. The Cao Dai Temple in Danang is at 63 Hai Phung, open daily dawn to dusk. You might have to wake somebody up to get inside, but someone is usually on-site with a key.
