Known simply as Swami Bagh, this huge white marble mausoleum , which houses the tomb of Sri Shiv Dayal Singh Seth, the founder of the Radhasoami Faith, is of particular interest because it is still being built – more than 80 years after it was started. Inside there’s a 1904 painting of what it should look like when finished, complete with a gold- latticed dome. For now it’s a work-in-progress project being undertaken by devotees. The design incorporates building styles from other major religions and includes some fabulously delicate floral carvings.
