The Budapest opera house is a beautiful Neo-Renaissance building opened in 1884. Construction included the use of marble and frescos by some of the best artisans of that era. Designed by Miklós Ybl, one of Europe's leading architects in the mid to late 19th century, the Budapest Opera House quickly became one of the most prestigious musical institutions in Europe. Many important artists performed here, including Gustav Mahler, who was also the director for three seasons.
The Budapest Opera House is considered to be amongst the best opera houses in the world in terms of its acoustics, and has an auditorium that seats 1200 people. It is horseshoe-shaped and, according to measurements done by a group of international engineers, has the third best acoustics amongst similar European venues (after the Scala in Milan and the Paris Opera House). The statue of Ferenc Erkel stands in front of the Opera House. He was the composer of the Hungarian national anthem and the first music director of the Opera. The other statue in front of the Budapest Opera is of Ferenc Liszt, the well-known Hungarian composer.References:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
