The Basilica de Santa Maria del Mar is one of Barcelona’s most stunning churches and a prime example of Catalan Gothic architecture. Its design showcases a cleaner, more restrained style compared to the elaborate ornamentation typically associated with Gothic structures. Construction began in 1329 and was completed in 1383 — an impressive feat for such a monumental project. Inside, the basilica feels remarkably spacious and airy, with its three naves of equal height supported by towering, slender pillars. The sparse decoration of the chapels enhances this sense of openness. Natural light filters through the magnificent rose window on the main façade and the vibrant stained glass windows, bathing the interior in a serene glow.

Typically octagonal, the stern-looking, neoclassical St George Cathedral was where Ethiopian rulers were inaugurated ever since its construction by the order of Emperor Menelik II, who dedicated the church to Ethiopia's patron saint, St George. Adjacent to the church is a museum with religious paraphernalia.

Rynek Główny is the name of the Main Market Square, which once was the largest square in Medieval Europe. It lies at the heart of the city and has been its hub, ever since the historical district of the Old Town got its present grid of streets in the 13th century. Rynek Główny is still very much the soul of the city.

On this rich archaeological site from the pre-Roman and Roman times about a hundred tombs have been discovered, out of which some date back from the 4th century B.C. According to the found artefacts and records of the Roman writers, experts identify this settlement as Arausona, a Liburnian-Roman settlement mentioned by Pliny. Tombs of the older layers of necropolis date back from the 3rd to the 1st century B.C., and they were made under the Hellenistic influence. A complex of blocks of houses made of fine carpeted stone, joined with clay, and later with mortar was also found here. The settlement was surrounded by defensive walls, made from the fractal stone, and was divided by streets. Some buildings had water tanks incised into the bedrock for collecting the rain-water.
