The square had previously been fenced in, making it difficult for pedestrians to get from Pilies Street in the Old Town to Gedemino Prospektas because of the narrow sidewalks. The drainage system beneath the square has been completely overhauled.
The granite was imported from Asia and covers 12,500 square meters of the total 16,000 square-meter surface. Darker strips of granite indicate former castle walls and other historical buildings.
Roughly 16 million litas ($4 million) in government funds was spent on the project. Lithuania's Castle Society intends to build a scale model of how the area looked in earlier times for permanent display in the square.
