GENERAL KNOWLEDGE

Detailed explanation-1: -When was the Taj Mahal built? Building of the Taj Mahal began about 1632. The mausoleum itself was completed by about 1638–39. The adjunct buildings were finished by 1643, and decoration work continued until at least 1647.

Detailed explanation-2: -The so-called “22 rooms” in the basement of the Taj Mahal are not really rooms, rather a long arched corridor along which doors were fixed so the space could be utilised better, sources in the Archaeological Survey of India (ASI) who have seen the basement area on several occasions, said.
