What a great city! Being from Canada, we were amazed at the history that exists here and throughout Scotland. This was our first trip to anywhere in Europe. We were amazed at the architecture, both its design and by how such amazing structures could have been created so many centuries ago with the primitive (by today's standards) technology available.
The buildings in the old and new towns represent different eras, but they are similar in that they are all pretty much the same height, and every spare inch of space is used. In spite of the uniformity of the building heights, the designs themselves vary. Each building has a unique facade and intricate stonework.
In spite of (or perhaps because of) the density of the buildings, the city is very walkable. All of the major tourist attractions are within a few blocks of each other. There is also an excellent transit system available.
One thing that is remarkable is that very few modern buildings exist. Most of the ones that do are inconspicuous as they are designed to appear old and fit in with the existing architecture. This may seem ideal to those of us from North America, where most old buildings have been torn down in the name of progress and new buildings are rarely built with any thought to how they fit into the existing environment. Many Scottish people we encountered, however, craved something modern (even the so called 'New Town' is 200 years old). They were sick of eveything being or looking old. After the initial novelty wears off, I could see how they might get sick of looking at these old buildings all of the time. Many of them are still covered in soot from the Victorian era when everbody burned coal for heat. The atmoshphere can be very drab and bleak, particularily on rainy days.
I doubt that this is a unique situation in Europe, so it shouldn't be used as an excuse to avoid Edinburgh. In spite of Glasgow's aspirations, Edinburgh remains the cultural capital of Scotland. There is a wealth of festivals, museums, historical sites, and shopping to keep you busy for at least a week. The Museum of Scotland/Royal Museum could keep you busy for 2-3 days on its own.
The week we spen in Edinburgh provided one of the highlights of our whole three week trip when we attended the Military Tattoo. The chaos of the Festival Fringe was also exciting. It was a stark contrast to the rest of our holiday, which was spent mostly in the country.
