The neoclassical Hellenic Parliament Building, standing prominently above the square, wasn’t always a government hub. Originally built in 1842 as the royal palace of King Otto, Greece’s first king, it housed the monarchy until 1923, when a severe housing crisis forced its transformation into a shelter for the poor. By 1926, the building officially became the headquarters of the Greek Parliament, and it has remained so ever since. Inside, it boasts a stunning library, which is well worth a visit if you’re interested in Greek history and politics.

👉 The Changing of the Guard. This is one of Athens’ most fascinating traditions. The Evzones, Greece’s elite Presidential Guard, stand watch 24/7 in their traditional pleated uniforms and pom-pom shoes. While the guard changes every hour, the full ceremonial parade happens every Sunday at 11 AM, featuring precision marching and an impressive show of discipline.

👉 Stick around after sunset. The Parliament building lights up beautifully at night, creating a completely different atmosphere from the daytime crowds. If you’re into photography, this is a great spot for capturing Athens after dark!
