Puja Mandala in Bali is a cool place where you can see 5 different religions coexisting peacefully. It's like a religious melting pot! You've got a Hindu temple, a grand mosque, a Buddhist temple, and even Catholic and Protestant churches all in one spot. It's pretty impressive to see how these different faiths come together in harmony. The complex is open to visitors, but you might have to check the schedule for each place of worship to see if you can go inside. Overall, it's a unique and fascinating place to visit in Nusa Dua.
