San Vito Lo Capo Lighthouse was built in 1859 under the period of the House of Bourbon who ruled the Kingdom of the Two Sicilies. The lighthouse consists of a white cylindrical tower, 38 metres high, with balcony and lantern, attached to the front seaside 1-storey white masonry keeper's house. The lantern, painted in grey metallic, is positioned at 45 metres above sea level and emits one white flash in a 5 seconds period, visible up to a distance of 19 nautical miles. Another light positioned at 12.5 metres emits a red flash on and off in a 4 seconds period. The lighthouse is completely automated.
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.
