Scotland is well known for its wealth of historical sites. Castles, monuments and religious edifices are top attractions in cities and towns throughout Scotland. It makes sense that many of the most famous historical structures are located in populated areas, as most places that were important centers of human activity in antiquity have only become more important through the centuries. But Scotland is also notable for having hugely important historical sites located in areas that have been left behind by the increasingly urbanized world. Many of the most awe-inspiring sites are nestled in rural or natural landscapes far from the noise and commotion of modern civilization. Despite their remoteness and isolation, these sites have been carefully preserved and protected. The combined effect on the visitor is a deeper and more soulful connection to Scotland’s rich history and natural environment. Such sites are often located on small islands where access is possible only by boat. The best way to visit a good number of these sites is on an expedition cruise to Scotland. Here are some must-see highlights of a cruise focusing on Scottish history and nature.
