Isa Khan’s tomb, which pre-dates the building of Emperor Humayun’s tomb, is significant for its profuse ornamentation – glazed tiles, plasterwork, stone elements such as finials and lattice screens. Conservation works in the Isa Khan’s garden tomb enclosure included reconstruction of the collapsed portions of the gateway; structural repairs to the garden retaining wall; restoration of the 2.5 m high finial on the dome; major structural repairs to the Mosque; de-silting of a well discovered here, amongst others. Stone finials to the canopies as well as the tiles that covered the canopy have been restored.
In 2016, eleven additional monuments which have benefitted from conservation and landscape restoration since 2007 have now been designated within the expanded World Heritage Site – which includes the Isa Khan’s Tomb-Garden.
An exhaustive documentation, condition assessment was prepared in 2010 and Conservation works commenced in early 2011 following a peer review of the Conservation Plan in July 2010.
Isa Khan’s tomb, which pre-dates the building of Emperor Humayun’s tomb, is significant for its profuse ornamentation – glazed tiles - much of which had sadly been lost. A detailed documentation and condition mapping, covering each tile remain was done to understand the original layout as well as the current status of the glazed tile work.
The discovery of original levels makes Isa Khan’s tomb garden the earliest surviving sunken garden of the Persian tradition. This revealed several terracotta objects, in addition to architectural elements, as well as the arcade of the enclosure wall, which is now once again visible as intended.
Though modern techniques have been used for documentation and presentation, conservation works have been carried out using traditional building materials prepared with traditional tools and techniques. The conservation philosophy has been to restore the original builders’ intention through conservation works, wherever the evidence remains.
After the major conservation works carried out for over two years with the co- funding by the World Monuments Fund, the opening ceremony of the 16th century Garden Tomb Complex of Isa Khan was held on the occasion of World Heritage Day on 18th April 2013. The tomb was unveiled by the Secretary- Culture, President and CEO of World Monument Fund and Director General, Archaeological Survey of India
Being strategically located at the entrance of the World Heritage Site of Humayun’s Tomb, there is significant visitor interest for the Isa Khan’s Tomb Enclosure. Regular heritage walks are conducted here by the Sair E Nizamuddin group for tourists and school children.
