The National Museum of Scotland is one of the Top 10 UK visitor attractions, and in the Top 20 of the most visited museums and galleries in the world. The museum houses a spectacular array of over 20,000 fascinating artefacts. The National Museum incorporates the collections of the former National Museum of Antiquities of Scotland, and the Royal Museum. As well as the national collections of Scottish archaeological finds and medieval objects, the museum contains artefacts from around the world, encompassing geology, archaeology, natural history, science, technology, art, and world cultures. The 16 new galleries reopened in 2011 include 8,000 objects, 80 per cent of which were not formerly on display. One of the more notable exhibits is the stuffed body of Dolly the sheep, the first successful clone of a mammal from an adult cell. Other highlights include Ancient Egyptian exhibitions, one of Elton John's extravagant suits and a large kinetic sculpture named the Millennium Clock. A Scottish invention that is a perennial favourite with school parties is The Maiden, an early form of guillotine.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
