The Basilica of Begoña started life in the 16th century, designed by Sancho Martínez de Arego. It has three naves, to which the addition of vaults was completed in the 17th century in construction work that took a century, having started in 1511. During the time of this work, the Gothic style began to show Renaissance influence, and the arched mid-16th century main entrance reflects the transitional style of the Spanish architect Gil de Hontañón. The remainder of the building remains purely Gothic in style.
During the 19th century, the basilica was damaged as a result of it forming part of Bilbao's city wall. The Carlist General Tomás de Zumalacárregui was fatally injured near the basilica. The current tower and part of the exterior were designed by José María Basterra and built between 1902 and 1907.
On 16 August 1942, an incident between Falangists and Carlists resulted in several grenades exploding near the church. Accounts differ on number of injuries and whether any were killed, but the incident highlighted dangerous rifts between Spanish nationalist factions and prompted a restructuring of Franco's government. A prominent Falangist, Juan José Domínguez, was controversially sentenced to death and executed by firing squad as a punishment for the incident.
Work was carried out to correct the damage, however, and from September 1993 to June 1994, extensive cleaning and restoration work was carried out on the stone and the clock face and bells were repaired. The clock tower houses 24 bells, with the heaviest weighing a tonne, and were built in Sumiswald, Switzerland. The history of the clock tower dates back to 1922, and currently, seven different melodies can be produced.
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.
