The Bilbao Fine Arts Museum is the second largest and most visited museum in the Basque Country, after the Bilbao Guggenheim Museum and one of the richest Spanish museums outside Madrid.

The Museum of Fine Arts in Bilbao was established in 1908. After moving through various venues, the final headquarters were built in 1945, in a great neoclassical building that was to undertake paths expansions in 1970 and 2001 to house the growing museum collection.
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.
