 The whole of the exterior is elaborately ornamented with glazed tile panels, string courses and battlements.Colors used are dark blue, azure, and white, contrasted with the deep red of the finely polished bricks.The tomb was said to have been built by Ghias-ud-Din Tughlak for himself, but was given up by his son Muhammad Tughlak in favour of Rukn-i-Alam, when he died in 1330.
