Iraqi Prime Minister Haider al-Abadi has ordered officials to open up to civilians the heavily-fortified area of Baghdad known as the Green Zone.
The 10km (four miles) sq area housing government buildings became off-limits to the public as a security measure in the wake of the 2003 US occupation.
It is the latest in a series of steps by Mr Abadi to ease sectarian tensions and crack down on corruption.
Baghdad has seen weeks of protests over poor services and abuses of power.
Earlier this month, in a rare show of unity, the Iraqi parliament backed Mr Abadi’s programme to abolish top government posts and cut spending.
On Friday, the prime minister issued instructions to lift restrictions on the Green Zone. It is not clear when the plan will be implemented.
