Standing in the centre of Warsaw’s Old Town is the imposing Royal Castle, home to Polish royalty for centuries. Built in the early 15th century in Gothic style, it is 90 metres long and is topped by bulbous spires. The building is currently a museum and houses a plethora of royal paintings, especially portraits. Facing the castle, in the middle of the square is the towering King Sigismund’s Column. It is a Corinthian column erected to honour one of Poland’s most important kings, responsible for moving the Polish capital from Krakow to Warsaw. Beyond the column is a set of ruins that could have been either a fort or city’s walls.
