Obviously, we believe that natural stone is a superior wall building material that is unmatched in its strength, durability and timeless beauty. The oldest stone wall has recently been discovered and has been standing at the entrance of a cave in Thessaly, Greece for the last 23,000 years. Gave us an idea to look up some famous stone walls that have been around for a while.
Walls of Avila (Spain): Built in the 11th century, these medieval walls, almost one and a half miles long, are still in good condition today. Fourteen meters high and as much as 3 meters thick, these walls have about 90 towers and 9 entrance gates.
The Walls of Constantinople (Turkey): The original walls were built in the 8th century BC and protected only the Greek acropolis. Constantine moved the walls further out and the present alignment was set in the 5th century AD. They extend 6.5 km from the Golden Horn to the Sea of Marmara. Despite lack of maintenance, many parts of the walls have survived centuries and are still standing today.
The Roman Walls of Lugo (Spain): The walls of Lugo were constructed over a period of 45 years between 265 AD and 310 AD the walls reach 10-15 meters in height, about 2 km in circumference and completely encircle the old town. The entire circuit survives intact and is the finest example of late Roman fortifications in Western Europe.
The City Wall of Visby (Sweden): Enclosing the Swedish town of Visby, this medieval wall was built in the 13th century and substantially modified in the 14th century. The wall is 11 meters high and 3.5 kilometers long and is still largely intact.
The Walls of Carcassonne (France): The historic French town of Carcassonne is a unique example of a double fortification with the town’s massive defenses constructed on walls dating from late antiquity to the 13th century. Very much intact, the inner wall measures 1286 meters and has 25 towers; the outer wall, with 17 towers, measures 1500 meters.
The Walls of Dubrovnik (Croatia): These defensive stone walls have been considered to be amongst the greatest fortification systems of the Middle Ages, as they were never breached by a hostile army during this time period. The intact city walls, constructed mainly during the 12th–17th centuries, run an uninterrupted course of approximately 1,940 meters (6,360 ft) in length, encircling most of the old city, and reach a maximum height of about 25 meters (82 ft).
Great Wall of China: Probably the world’s most famous stone wall, the Great Wall of China, is also the world’s longest (over 4000 miles) and largest human-made structure ever built in terms of surface area and mass. With wall sections dating back to 208 BC, this wall is a true testament to the amazing everlasting durability of stone.
