This tower along Greengate Street (and Hole in the Wall Street on the other side) is the southeast corner of the medieval wall. In the background is the Northeast Tower of Caernarfon Castle. It is appropriate to show them together because they were built simultaneously in 1285 based on the plans of architect James of St. George. Hundreds of English workers were employed to construct these massive defenses within a few years. They remain Wale’s finest historic strongholds.
