The outlook onto Edinburgh Castle from Waverley Bridge, onto Salisbury Crags from the Pleasance and onto the Meadows and the castle from the Meadows and Bruntsfield Links have been granted special status in response to public demand.
They join views such as those of Arthur's Seat and the New Town from various vantage points to be protected by the planning system.
The success of the Edinburgh World Heritage Trust-funded study to find the capital's best-loved views has encouraged Edinburgh City Council to plan a similar study on the Forth bridges.
"Edinburgh's skyline is cited by UNESCO as one of the most significant values of the world heritage site. The public obviously agrees," said director of city development Andrew Holmes.
"It is recognised that the bridges, and especially the rail bridge, have iconic status and should therefore be considered," he added.
