The Church of the Ascension is an Episcopal church built in 1840–41. It was the first church to be built on Fifth Avenue and was designed by Richard Upjohn in the Gothic Revival style. The interior was remodeled by Stanford White in 1885–88.
The brownstone church is symmetrical, and features a square tower. Stanford White's interior design features a pulpit designed by Charles Follen McKim, mosaics by D. Maitland Armstrong, a marble reredos by Louis Saint-Gaudens and several stained glass windows by John LaFarge and his altar mural The Ascension. This is considered to be one of his best works
The parish house designed by McKim, Mead and White took a previously existing building and turned it into a Northern Renaissance-inspired building of yellow brick with bottle-glass windows.
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.
