The construction of Humayun's tomb was taken up by the grief-stricken wife of Humayun, Hamida Banu, also known as Bega Begam in 1565. Legend has it that the design of the Taj was inspired from this tomb's. In pure architectural sense, this building is probably superior and much more beautiful that the stunning Taj. Sacrilege? But really, the only thing this building lacks is the showy marble.

Further down is the Jamali Kamali masjid and tomb, which has recently been renovated by INTACH, an autonomous cultural organization. Jamali was the alias of the Sufi saint Shaikh Fazlullah, who was also known as Jalal Khan. The saint had a prodigious life – he lived right through Sikander Lodi's reign, the famous battle of Panipat in 1526, Babur and died during the lifetime of Humayun. Who Kamali was remains a tantalizing mystery.

On way to the masjid, a short distance away you'll probably spot the tombs of Sheikh Alauddin (died 1541-42), descendant of the famous Sufi saint Shaikh Faridu'd-din Shakarganj and Shiekh Yusuf Qattal (died 1527) who was a disciple of Qazi Jalaluddin of Lahore.

About 8km from the Qutub Minar, on road from andheria More, is Sultan Ghari's tomb. It was built by Altamash in 1231 for his son and heir-apparent Nasiruddin Mahmud, who died in battle in 1229 in Lakhnauti (Lucknow). It is built in the same style as the Quwwat-ul-Islam mosque and is assembled from assorted destroyed Hindu temples and other buildings.

In the same complex is the tomb of Shams-ud-din Altamash (1211-36), the son-in-law and successor of Qutub-ud-din Aibak. Altamash is widely regarded as the real founder of the Delhi sultanate and had a very successful reign (see history).
His tomb was built in 1235 and is quite an interesting example of Islamic architecture in India. It marks the phase when the sultans had stopped spare parts from broken temples for their buildings. The building was made from foundation up and not assembled.
It seems that there had been plans to cover the tomb chamber with a dome, as is obvious from the squinches which make their first appearance in this building. It is said, once the dome fell but was replaced by Feroze Shah Tughlaq and then again fell down, beating even his patience for it was not replaced.

Inside the tomb there are three mihrabs (prayer niches). The central one of these is located higher than the other two and is profusely decorated with marble. The tomb itself is quite simple, but its entrance is intricately carved with geometrical and arabesque patterns. There are some Hindu motifs too though – like wheels, the lotus, diamonds and so on.

South to the fortress of Tughlaqabad is the tomb of its builder, Ghiyasuddin Tughlaq. A once fortified causeway lead to the tomb compound, which at one time stood within a large reservoir. Ghiyas-ud-din Tughlaq was obviously a man of set ideas – while he was about fortifying everything in sight, he fortified his tomb as well. What against is hard to say; probably Mongols who took the term happy hunting grounds too literally.
The reservoir is no longer stores any water and the bridge over it has been broken off in the middle to make way for an extremely busy road. The tomb is based roughly on a pentagon in plan and its entrance is guarded by massive portals.
