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...

This site we discover with the audioguide (audioguides) has been occupied by different religious buildings since the Roman era.

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.

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 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...

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.

Audioguide of Pompeii

We begin our journey of discovery in the city of Pompeii with a brief introduction from the audioguide. One fine day in 1550, while digging a new course for the Sarno River south of Naples, the Italian architect, Domenico Fontana, found a surprise under his feet: Pompeii, one of the most important cities of Classical Antiquity. Since then, archaeologists have not stopped working to bring the city we are going to visit back to life. Geographically, we are in southwest Italy, in the Campania region, and at the foot of Mount Vesuvius, an active volcano that has many tales to tell. This mountain has given its name to the Vesuvian volcanic explosions, which are characterized by the formation of clouds that turn into ash precipitation, which can even bury entire cities. It looks like a movie, doesn't it? Well, that's what happened with Pompeii. The city of Pompeii, along with the nearby towns of Herculaneum and Stabia, was buried by the ashes of a powerful explosion from the nearby volcano in 79 A.D. Oh, yes, right in the heart of the Roman Empire, surprising the inhabitants in the midst of their daily chores...

This Hamburg audio guide will help you to visit one of the most important and vibrant cities in Germany. Will you accompany me with this audioguide? Since Hamburg joined the Hanseatic League in the Middle Ages, it has always been a city dedicated to trade with the rest of the world. It reached its splendor as a center of international trade during the 19th and early 20th centuries, only to fall into oblivion after the devastation it suffered due to the Allied bombings during World War II. More than 70% of the city was reduced to rubble by the bombs that the English and Americans dropped on Hamburg during Operation Gomorrah. Tenacity and hard work - classic Germanic values - managed to rebuild a city that became rich again thanks to its great commercial port traffic. Not surprisingly, its cargo port is the second busiest in Europe - after Rotterdam - and the ninth in the world...

Audioguide of Stuttgart

Located in the heart of the city, it is a vibrant meeting point and an epicenter of cultural and social activity. This spacious square is the ideal starting point for exploring the rich history and modern dynamism of Stuttgart.
Dominating the Schlossplatz is the impressive Neues Schloss, an 18th-century Baroque palace that testifies to the opulence of the former dukes of Württemberg. Although it suffered damage during World War II, it has been meticulously restored, serving today as a fascinating testament to the city's historical resilience.
Facing the Neues Schloss is the Jubiläumssäule, a column erected in 1841 to commemorate the 25th anniversary of King William I of Württemberg's reign. Crowned by the statue of Concordia, the goddess of harmony and unity, this column has become an iconic symbol of the city.

Audioguide of Trier

Imagine a place where the shadows of the past blend with modern bustle, where ancient stones whisper tales of emperors and gladiators. Welcome to Augusta Treverorum, known today as Trier, one of Germany's oldest cities, with a history that stretches back over two thousand years.
According to legend, the city was founded much earlier than the Roman era by Trebeta, a prince from the Assyrian Empire, an ancient region of Upper Mesopotamia. The legend tells that he fled his homeland and founded a city in the unknown lands of Europe, which would later become known as Trier, approximately 1,300 years before the founding of Rome. Of course, this is a story that challenges the historical record and is probably best enjoyed with a pinch of imagination and a good Moselle wine in hand.
Our journey begins when a Celtic tribe, the Treveri, decided to settle along the winding Moselle River.
