It was carved out of natural rock in memory of the heroic deaths of the Swiss mercenaries at the Tuileries in 1792. Mark Twain described the Lion of Lucerne as the saddest and most moving piece of rock in the world. The Lion lies in his lair in the perpendicular face of a low cliff — for he is carved from the living rock of the cliff. His size is colossal, his attitude is noble. His head is bowed, the broken spear is sticking in his shoulder, his protecting paw rests upon the lilies of France. Vines hang down the cliff and wave in the wind, and a clear stream trickles from above and empties into a pond at the base, and in the smooth surface of the pond the lion is mirrored, among the water-lilies. Around about are green trees and grass. The place is a sheltered, reposeful woodland

LOOKING LIKE SOMETHING STRAIGHT OUT of Game of Thrones, the Puente Nuevo spans a narrow chasm that separates two sides of the historic city of Ronda.It was the first attempt at bridging the canyon at this height, and it was no easy feat. The chasm was relatively narrow, but plunged some 390 feet straight down to the Guadalevín River below.
The architects Jose Garcia and Juan Camacho were chosen for the project, and they began work on a single arch design in 1735. During the 1936–1939 civil war, which heavily affected Ronda, captured prisoners were allegedly tortured in the chamber. Some, apparently, were thrown from the windows of the chamber, to break upon the rocks of the El Tajo gorge far below.
A scene in Hemingway’s For Whom the Bell Tolls, in which Fascist sympathizers are thrown from the cliffs of a fictional village, is believed to have been inspired by events in Ronda.

In the Golden Age of the city in order to house the ancient wooden cult statue of Athena and generally glorify the great city at the height of its power and influence. The Erechtheion has suffered a troubled history of misuse and neglect, but with its prominent position above the city and porch of six Caryatids, it remains one of the most distinctive buildings from antiquity.
The Erechtheion, named after the demi-god Erechtheus, the mythical Athenian king, was conceived as a suitable structure to house the ancient wooden cult statue of Athena, which maintained its religious significance despite the arrival of the gigantic chryselephantine statue within the nearby Parthenon. The building also had other functions, though, notably as the shrine centre for other more ancient cults: to Erechtheus, his brother Boutes - the Ploughman, Pandrosos, the mythical first Athenian king Kekrops (or Cecrops) - half-man, half-snake, and the gods Hephaistos and Poseidon.
As with the other new buildings on the acropolis, the Erechtheion was built from Pentelic marble which came from the nearby Mt. Pentelicus and was celebrated for its pure white appearance and fine grain. It also contains traces of iron which over time have oxidised, giving the marble a soft honey colour, a quality particularly evident at sunrise and sunset.

It stands on a triangular basaltic spur. The walls of the castle just like its 7 towers are made of ancient gray lava blocks while the roofs are covered with stone slabs. The first fortification at the site was a wooden tower protected by a wall and a dry moat – actually this is now the only side one can access the chateau. In the early 11th c. the Lords of Sailhant replaced the wooden tower with a square stone keep. The Saillans family kept expanding the fortress – by the 13th c. the spur was closed off by a curtain wall with ramparts and 2 towers and a deep, dry moat. By the 18th c. the chateau was in a dilapidated state, some structures were demolished. In 1997 the ruined castle was bought by architect Joseph Pell Lombardi from New York, who made it his residence following 25 years of restoration efforts.
