Psyrri is a gentrified neighbourhood known for its bohemian cafe-bars, live music taverns, artisanal boutiques, exotic spice bazaars and small number of hotels. It's one of the oldest quarters of Athens and used to be regarded as a dodgy place until the early 90s. In the late 19th century, Psyrri used to be the ‘Bronx’ of Athens. ‘Koutsavakides’, ‘hobbler dudes’ in Greek, would walk the streets in their jackets worn on one sleeve and bully locals. You'll see this archetypical character show up in street art all over the neighbourhood.

Named after Erechtheus, king of Athens and foster son of Athena, the Erechtheion is an ancient Greek temple on the north side of the Acropolis dedicated to both Athena and Poseidon. This intricate temple was designed to accommodate the radically uneven ground on the site and to avoid disturbing sacred shrines like the altars to Poseidon, the sacred olive tree, a well containing sea water, the tomb of Kekrops, and the Pandrosion sanctuary.

The treasury of Aachen Cathedral is regarded as the most important north of the Alps, featuring over 100 art pieces across various themes. Highlights include the Cross of Lothair, the Bust of Charlemagne, and the Proserpina sarcophagus. The museum offers a remarkable insight into religious and historical art.

This fortress was ordered to be constructed by the legendary Richard Lionheart. It boasts spectacular views over the Seine River and will keep both adults and kids entertained while exploring the area. The château still stands 8 centuries after its inauguration, and is a major attraction despite the grim stories of its involuntary residents.
