The Archaeological Survey of India (ASI) on Friday resumed its scientific survey of the Gyanvapi premises here to determine whether the 17th-century mosque was constructed over a pre-existing structure of a Hindu temple.
The Allahabad High Court had on Thursday allowed the ASI to conduct the survey.
The survey, which was boycotted by members of the Anjuman Intezamia Masjid committee, began at 7 am, ASI sources said.
