Expansion projects worth $133.3bn (SAR500bn), currently underway in Madinah, are progressing as scheduled, Prince Faisal bin Salman, governor of the city, announced.
Prince Faisal said this construction data includes the extension to the Prophet's Mosque and various health services and security projects approved by Custodian of the Two Holy Mosques King Salman.
He added that the city's administrators have formed a committee to execute and monitor all projects in the city.
The committee is to ensure that all contractors working in Saudi "respect and protect the city's Islamic architectural heritage", local daily Arab News reported.
"These sites and treasures are cared for and documented by the Saudi Commission for Tourism and National Heritage (SCTNH)," he said.
Earlier this year, King Salman approved the Darb Al-Sunnah Project, which is being developed under the Madinah Development Authority, according to Prince Faisal, the president of the body.
Prince Faisal had thanked the King for approving the 3km development between the Prophet's Mosque and Quba Mosque.
He said the project takes into account palm farms surrounding the mosque, which would provide visitors and residents with recreational facilities, the report added.
