In addition to sites inscribed on the UNESCO World Heritage list, member states can maintain a list of tentative sites that they may consider for nomination. Nominations for the World Heritage list are only accepted if the site was previously listed on the tentative list. Portugal recorded 21 sites on its tentative list. Some of them are listed below.
Any of these locations can be visited on our private tours from Lisbon. Tell us what you would like to visit and we will present you a complete program for a day trip.
