Martinsburg Castle with its powerful hexagonal tower was built around 1324 as a toll station on the Rhine bank in Oberlahnstein. It was a toll castle in the Electorate of Mainz. The pictorial assembly was built together with the town fortification.
The pointed gate in the east wall shows a delicate cast iron oriel with emblem (1395). The north wing probably contained the main rooms. The apartment tower in the northwest, built in the 14th century, was modified in the 18th century. The south wing is likewise Gothic. The archbishop Franz Lothar von Schönborn established the southwest and west wing between 1719 and 1721; there the main tower (end of the 14th century) is assembled; at its windows one sees outside small console stones for the fold-down wooden shutters. The roof dates from the 18th century.References:
The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
