AGRA, INDIA—Remains of a summer palace have been uncovered in the area opposite the Taj Mahal. The building is thought to have been a baradari, a pavilion designed to allow the free flow of air, set in the Mughal-era garden Mehtab Bagh, reportedly Shah Jahan’s favorite spot for its view of the Taj at night. “The present work is going in the south direction of the garden in the straight alignment of the Taj Mahal which makes the discovery an interesting one,” an official from the Archaeological Survey of India told The Times of India. The summer palace may have been inundated by flooding of the Yamuna River.
