We continued our sightseeing along Prince Street to Carlton Hill. In addition to the city's scenery, there are several buildings on the top of the mountain that can be called scenic spots but not charged. Among them is the National Memorial Hall, which is said to be built in memory of the soldiers killed in the Napoleonic War. This Greek Parthenon-like building was built in 1826, but it was not completed. Now only a row of huge pillars supporting the beams can be seen. The reason is that there is not enough money to raise, and now it is like "uncompleted project" staying at the top of Carlton Hill. Next to it is the Nelson Memorial Tower, which allows you to view Edinburgh downtown from the top, but requires a 5 pound ticket. On the top of the hill is the memorial Pavilion of the Scottish philosopher Dugard Stewart. Several stone pillars are beautifully shaped with domes, but they are surrounded by weeds. There is also a striking dome nearby, the Edinburgh Municipal Observatory, which is not open inside.
