The West Port is a street in Edinburgh's Old Town, Scotland, located just south of Edinburgh Castle. It runs from Main Point (the junction of Bread Street, Lauriston Street, East Fountainbridge and High Riggs) down to the south west corner of the Grassmarket. Its name derives from the fact it sloped up from the town gate named the West Port, which was the only westwards exit from the city when the city walls stood, allowing passage through the Flodden Wall.
