The Basilica della Santissima Trinità di Saccargia is a church in the comune of Codrongianos, northern Sardinia. It is the most important Romanesque site in the island. The construction is entirely in local stone (black basalt and white limestone), with a typical appearance of Tuscan Romanesque style.
The church was finished in 1116 over the ruins of a pre-existing monastery, and consecrated on October 5 of the same year. Its construction was ordered by the giudice (judge) of Torres. It was entrusted to Camaldolese monks who here founded an abbey. It was later enlarged in Pisane style, including the addition of the tall bell tower. The portico on the façade is also probably a late addition, and is attributed to workers from Lucca.
The church was abandoned in the 16th century, until it was restored and reopened in the early 20th century.
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.
