The Lotus Temple reminded us all of The Opera House in Sydney, all the way down to the scale-like details. It was also interesting to note that the temple was surrounded by large pools - of course, because lotuses grow in water.
On the last day we went to see the Lotus Temple. I was thrilled to see a religious/cultural site in Delhi, as I thought that I wasn't going to have time. The gardens lining the pathways were also an unexpected delight.
