The Taj Mahal is a composition of approaches, planting, water, stone and sky. The celebrated central view is one way to read it; a closer look at surface detail gives a very different impression of the workmanship. Notice how the surrounding elements make the mausoleum feel balanced, rather than treating them simply as foreground for a photograph.
Set aside time for the approach and the closer architectural details. Decide which light matters to you before choosing an entry time.
