By this time Islamic architecture in India had adopted some features of earlier Indian architecture, such as the use of a high plinth, and often mouldings around its edges, as well as columns and brackets and hypostyle halls. After the death of Firoz the Tughlaqs declined, and the following Delhi dynasties were weak. Most of the monumental buildings constructed were tombs, although the impressive Lodi Gardens in Delhi (adorned with fountains, "charbagh" gardens, ponds, tombs and mosques) were constructed by the late Lodi dynasty. The architecture of other regional Muslim states was often more impressive.
