The National Wallace Monument is which commemorates Sir William Wallace, a 13th-century Scottish hero. The tower was constructed following a fundraising campaign, which accompanied a resurgence of Scottish national identity in the 19th century. Completed in 1869 to the designs of architect John Thomas Rochead at a cost of £18,000, the monument is a 67-metre sandstone tower, built in the Victorian Gothic style.
The tower stands on the Abbey Craig, a volcanic crag above Cambuskenneth Abbey, from which Wallace was said to have watched the gathering of the army of King Edward I of England, just before the Battle of Stirling Bridge. The monument is open to the general public. Visitors climb the 246 step spiral staircase to the viewing gallery inside the monument's crown, which provides expansive views of the Ochil Hills and the Forth Valley.
A number of artifacts believed to have belonged to Wallace are on display inside the monument, including the Wallace Sword, a 1.63-metre long sword weighing almost three kilograms. Inside is also a Hall of Heroes, a series of busts of famous Scots, effectively a small national Hall of Fame.
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.
