The Arch of Titus was constructed in c. 82 AD by the Emperor Domitian shortly after the death of his older brother Titus to commemorate Titus's victories, including the Siege of Jerusalem (AD 70). The arch has provided the general model for many triumphal arches erected since the 16th century, perhaps most famously it is the inspiration for the Arc de Triomphe in Paris, France.
The Frangipani family turned the arch into a fortified tower in the Middle Ages. It was one of the first buildings sustaining a modern restoration, starting with Raffaele Stern in 1817 and continued by Valadier under Pius VII in 1821, with new capitals and with travertine masonry, distinguishable from the original.
References:Linderhof is the smallest of the three palaces built by King Ludwig II of Bavaria and the only one which he lived to see completed.
Ludwig II, who was crowned king in 1864, began his building activities in 1867-1868 by redesigning his rooms in the Munich Residenz and laying the foundation stone of Neuschwanstein Castle. In 1868 he was already making his first plans for Linderhof. However, neither the palace modelled on Versailles that was to be sited on the floor of the valley nor the large Byzantine palace envisaged by Ludwig II were ever built.
Instead, the new building developed around the forester's house belonging to his father Maximilian II, which was located in the open space in front of the present palace and was used by the king when crown prince on hunting expeditions with his father.
