Mausoleum of Imam Yahya ibn al-Qasim - tomb on the right bank of the River Tigris built by Badr al-Din Lu?lu, a 13th century Mamluk sultan of Mosul. Badr al-Din was a Shia, and so was the Imam who he honored in 1239 with a massive mausoleum on the banks of the Tigris. At one stage riverbank erosion caused the structure to begin leaning and massive buttresses had to be constructed to keep it from collapsing into the river. Its interior was decorated with ornate carvings, mosaics and architectural features, all of which are now gone since it was totally destroyed by ISIS in July 2014.
