The Boulevard of Heroes was a landmark on the planet Romulus.
It was noted as being so large that it was capable of being seen from space and ran from the shores of the Havrelar Sea to the center of Val'danadex Trel. Monuments along with statues honoring the greatest Romulans in history lined the grassy median. These included an enormous statue dedicated to Emperor Salangen at Setalep IV, the Laneshra Monument and the Mausoleum of Reldek the Great amongst many others.
Many shops both elegant and quaint filled both sides of the street and the broad sidewalks always bustled with people. (Last Unicorn RPG module: The Way of D'era: The Romulan Star Empire)
