I visited Sarkhej Roza, while on my journey with Karwan-e-Mohabbat. It is a tomb complex, once a prominent center for Sufi culture.

From wikipedia:
Sarkhej Roza is a mosque and tomb complex located in the village of Makarba, 7 km south-west of Ahmedabad in Gujarat state, India.
Although there are many rozas[1] across Gujarat, the Sarkhej Roza is the most revered. Sarkhej was once a prominent centre of Sufi culture in the country, where influential Sufi saint Shaikh Ahmed Ganj Baksh lived. It was on the saint’s suggestion that Sultan Ahmed Shah set up his capital on the banks of the Sabarmati, a few miles away from Sarkhej.
I do not know much about the monument but what I learnt from my visit is that it is unique to have a fusion of Hindu and Muslim architecture. For example motifs of flowers, animals is not allowed in Islam but these are Hindu symbolism that have bene used in this monument.
During my visit, I did not see many tourists to the place and it seemed Sarkhej Roza is not a very popular place to visit which is not a surprise. The Hindu nationalist government of Narendra Modi and RSS-BJP combine tends to ignore the Mughal heritage and culture.
