The Plaza of the Endless Sky was a location on the planet Romulus and situated in the capital of Val'danadex Trel. The Boulevard of Heroes terminated at the Plaza which was in the middle of the city. It was an open area that was more than two square kilometers wide and broad. The Plaza was the center of Romulan politics and much of the city's social life was focused in the area. Many events as well as festivals were hosted here and on most days thousands of Romlus came here to simply enjoy the sunshine along with the fresh air. On some of the other days, they came to attend a military parade or a speech by the Praetor or some other major civic event. (Last Unicorn RPG module: The Way of D'era: The Romulan Star Empire)
