We visited the Eiffel Tower , UNESCO headquarters and sailed down the river Seine on a bateau - mouche and that was only day one . The next day we had to walk as the transport workers were on strike ( strike in France - unusual ! ! ) . We went to the Opera House which was perhaps the most beautiful building ever and shopped in the Galaries Lafayette ( Paris ' most famous department store ) . In the afternoon we visited the Sacre - Coeur and lunched in the Place du Tertre .
