Audioguide of London

Saint Edward the Confessor ordered the construction of a palace on the borders of the River Thames to use as his residence at the end of the 11th century. A fire destroyed part of the building in 1529 which prompted the residing king, Henry VIII, to move to another palace. Since then, it has been used by the two Houses of Parliament and the Court of Justice. Another terrible fire, this time caused by a stove in the House of Lords, almost completely destroyed the palace in 1834. After the catastrophe, the palace was rebuilt from the ground up, and the few structures that remained were conserved. During World War II, the Germans succeeded in bombing the House of Commons. At present, the palace you can visit with the audioguide (audioguides) consists of about 1,200 rooms...

Audioguide of Paris

This site we discover with the audioguide (audioguides) has been occupied by different religious buildings since the Roman era. First, there was a temple dedicated to Jupiter, then an early medieval church in the 6th century called Saint-Etienne, and later a Romanesque church. The structure we can see today was dedicated to the Virgin Mary and was built between 1163 and 1245 in a Gothic style. It has been renovated several times during its 800-year history, the most significant of which was undertaken in the 19th century to repair damage from the French Revolution.
Its famous gargoyles have been rebuilt. Furthmore, various parts of the structure such as the steeple of the dome have been restored, which features a bronze rooster adorned with three relics sitting on a cross. At 93 meters high, it serves as a kind of spiritual lightning rod that protects the faithful of Notre Dame during thunderstorms...

Audioguide of Rome

The Colosseum is symbolic to Rome. Entering its gates with the audioguide (audioguides) takes you back 2,000 years to the most majestic and splendid era of the Roman Empire. Under the motto "Pan et Circus", the Roman Colosseum, which was initially known as the Flavio Amphitheater, allowed more than 50,000 people to enjoy spectacles such as war recreations, exotic animal displays, prisoner executions and gladiatorial battles to the death. Its construction began in 72 AD under the rule of Emperor Vespasian and ended in 80 AD during the mandate of Emperor Tito. Tito inaugurated the edifice with 100 days of lavish games which cost the lives of over 2,000 gladiators. The Colosseum became the largest amphitheater of the empire. It featured a canvas roof to protect the public from the sun, while machinery and cages were buried under the sand...

Audioguide of Florence    

Construction of the city cathedral began in 1296. Upon its completion 72 years later, it was the largest building in Europe. The black plague that laid waste to the city occurred during its construction. Its name comes from the lily flower, which is a symbol of Florence and part of its flag. Crowning the edifice is a great dome, which was built almost a century later by Filippo Brunelleschi. Its design was inspired by the Pantheon of Rome, which full audioguide (audioguides) is available on our website. Due to the excessive weight of the Dome, Brunelleschi studied for years to invent a new and ingenious masonry method which was based on using a composition of crossing bricks. The result was a double self-supporting dome, measuring 114 meters high and containing 463 steps. The last flight of stairs at the top of the dome is almost vertical between the interior and exterior cupola...

Audioguide of Berlin

At the end of World War II, the allies divided Berlin into four sectors: the French, English, American, and Soviet. Shortly afterward, the western sectors united to become the Federal Republic of Germany (FRG), while Russia constituted the German Democratic Republic (GDR) to the east. Each state followed a distinct socio-economic model. Emigration from east to west proliferated, with almost 3 million people crossing the border over time. As a result, in the dead of night on August 12, 1961, the Soviets erected a temporary fence that ran 155 km across the city. With it, they could secure 69 of the 81 control points that provided access between the two sections over the city. Over the next few days, the Soviets would replace the clandestine fence with an imposing brick wall, described in this audioguide (audioguides), forcibly evicting the residents whose houses stood in the way...

Audioguide of Lisbon

This tower was built in 1515 in honor of the patron saint of Lisbon, Saint Vincent. Over time, it would become one of the most representative examples of Manueline architecture. Due to its strategic location at the mouth of the Tagus, it was first used as a defense tower to protect the entrance of the port. From this region, many explorers would roam the oceans in search of new lands and maritime routes in Asia, Africa and Americas. Its use changed as the years passed. For a period it served as a customs office, then later as a jail to house political prisoners. The tower is divided into five floors that you can visit with the audioguide (audioguides). On the first three, we can see the Governor's Hall, the Hall of the Kings and the Audience Hall. On the fourth and fifth floors are the Chapel and the Terrace...

Audio guide of Zaragoza

We are with the audioguide (audioguides) in front of the Aljafería, the most important Islamic civil construction of the XI century which was erected as a leisure palace by the Muslim monarchs of Zaragoza. It was also the headquarters of the first order cultural court, where King Al-Muqtadir surrounded himself with scientists and intellectuals, turning it into one of the most exciting periods in the city's history. We can still recall the splendour of the taifal palace when entering the Patio of Santa Isabel, strolling past the orange trees, under the arcades, looking out the oratory and contemplating its entirety from the Golden Room. It is worth stopping with the audioguide (audioguides) at the oratory or mihrab, which faces the Mecca and is of small dimensions due to its private use.In this area, the mixtilinear and multi-foliated arches of indisputable quality are also worth mentioning, making La Aljafería...

Audio guide of Aranjuez (dramatized and for children)

The first Spanish Habsburgs established the itinerant Castilian court in the centre of Spain, and Aranjuez - between Toledo and Spain - became the regular residence of Emperor Charles V; subsequently, Phillip II of Spain came up with the idea of a system of Royal Sites around the new capital. The court would remain in Madrid during the winter and it would embark on the Royal Progresses the rest of the year: Aranjuez in spring, Escorial in summer and Granja in autumn. Throughout Europe, royal sites were a display of the most refined architecture, gardening and decorative arts. King Ferdinand VI and his wife Barbara of Portugal were deeply in love with the city described in this audioguide (audioguides), and during their pacific reign, astounding celebrations were the norm in a courtly, populous, comfortable and cheerful town. During the reign of CHARLES III...
