Discuss how Akbar's mausoleum at Sikandra and the tomb of Itimad-ud-Daula show that jahangir's contribution to the building art was rather insignificant when compared to the vast and ambitious perfects of his father, on the one hand, and those of his son, on the other.

Jahangir’s contributions to the building art appear to have been rather insignificant when compared to the vast and ambitious projects of his father on the one hand, and those of his son on the other. His inclination was more towards the art of painting than towards building.
During the early period of his reign, Jahangir had to take a certain personal interest in building art as the production and completion of the mausoleum, which his father had planned as his last resting place, devolved upon him.
Akbar’s mausoleum stands at Sikandra, 5 miles west of Agra. The Emperor did not live to carry his remarkable project to completion, a task that had to be done by his son Jahangir. As it now stands, the mausoleum lacks the homogenity and balance, which constitute the essential keynotes of Akbar’s building style.
Towards the end of Jahangir reign was constructed the mausoleum of Itimad-ud-Daula, father of Nur Jahan, the queen of Jahangir. The tomb of Itimad-ud-Daula is of significant interest in the history of Mughal architecture as supplying a link between its two important phases, namely those of Akbar and of Shah Jahan. It represents the transition from the red sandstone phase of Akbar’s to the usage of marble by Shah Jahan.
