In 1536 Louis X, Duke of Bavaria laid the foundation stone for a new residence in the inner city of Landshut. It was begun in German Renaissance style under the architect Bernhard Zwitzel from Augsburg. During a journey to Italy the duke got the inspiration for an additional palace.
Behind the German building, close to the river Isar, the so-called 'Italian building' was constructed from 1537 to 1543 in Italian Renaissance style with a spacious courtyard and the palace chapel. It was modeled in particular after the Palazzo Te in Mantua, and was the first Italian style palace erected north of the Alps. Both buildings were connected by two wings. The paintings in the rooms were created by the Germans Hermanus Posthumus, Hans Bocksberger the Elder and Ludwig Refinger, while the stucco was done by Italian artists.
When Count William of Birkenfeld-Gellnhausen, who became later the first Duke in Bavaria, resided in the palace from 1780 onwards the facade of the German building was altered in French Neo-classical style and the so-called 'Birkenfeld Rooms' were constructed. These rooms were decorated again with early wallpaper, when Crown Prince Ludwig lived here in the early 19th century, in the course of his studies in Landshut. These rooms are today a part of the Residence Museum, together with the halls of the Italian building.References:
The Arch of Constantine is situated between the Colosseum and the Palatine Hill. It was erected by the Roman Senate to commemorate Constantine I's victory over Maxentius at the Battle of Milvian Bridge in 312. Dedicated in 315, it is the largest Roman triumphal arch. The arch spans the Via triumphalis, the way taken by the emperors when they entered the city in triumph.
Though dedicated to Constantine, much of the decorative material incorporated earlier work from the time of the emperors Trajan (98-117), Hadrian (117-138) and Marcus Aurelius (161-180), and is thus a collage. The last of the existing triumphal arches in Rome, it is also the only one to make extensive use of spolia, reusing several major reliefs from 2nd century imperial monuments, which give a striking and famous stylistic contrast to the sculpture newly created for the arch.
The arch is 21 m high, 25.9 m wide and 7.4 m deep. Above the archways is placed the attic, composed of brickwork reveted (faced) with marble. A staircase within the arch is entered from a door at some height from the ground, on the west side, facing the Palatine Hill. The general design with a main part structured by detached columns and an attic with the main inscription above is modelled after the example of the Arch of Septimius Severus on the Roman Forum.
