Aristotelous Square is the most impressive square in Thessaloniki. It features buildings with monumental architecture inspired by European and colonial models, cafes, shops and restaurants. It is the focal point in big celebrations, such as the coming of the New Year, and is the de facto meeting place during the day. The history of Aristotelous Square began with the Great Fire of 1917 that destroyed two thirds of the city. The French architect Ernest Hébrard designed Aristotelous Square to serve as an end of a monumental axis for Thessaloniki that would stretch from the seafront to Dikastirion Square and the Roman Forum. The final design, built in the 1950s, is a lot more stripped down than Hébrard's original proposal, but still has significant architectural value.

Built between the years of 1628 and 1633, St Columb’s Protestant Cathedral is the oldest surviving building in Derry. It's monumental appearance conceals a cosy, intimate interior, and the nearby Chapter House contains a number of historic artefacts.

The Museo de la Memoria y los Derechos Humanos illustrates General Augusto Pinochet's 17-year dictatorship over Chile that resulted in the murder of thousands of Chileans. The museum contributes to the reworking of the period between 1973 and 1990 and at the same time, honours the many victims of the Pinochet rule. It stands as a landmark for the creation of cultural awareness and educates about the terrors of dictatorship.

The Altamura Cathedral, dedicated to the Assumption of the Blessed Virgin Mary, was founded by Emperor Frederick II of Swabia in 1232. This is an important symbol of the town's history and one of the four Palatine cathedrals of Puglia (the others are San Nicola in Bari, Barletta Cathedral, and Acquaviva Cathedral). The Cathedral has gone through major changes and is today an interesting tourist attraction.
