actually now I think about it, I like all religion's churches - some modern Christian ones I don't go for, but I have been in Sikh, Taoist, Buddhist, Muslim, Christian and Hindu temples/churches/mosques, and the old ones especially I really like - but as I say, not when they are full of people.
I don't go for many of the services - not keen on the Muslim and Christian services. Sikh services are beautiful, and of course the Tibetan Buddhist ones are fabulous. Taoist services are either boring or weird. Hindu services are good fun if you don't mind the noise.
