The Byward Tower and The Outer Ward
The Byward Tower probably derives its name from by-the-ward, and gives access to the Outer Ward. It is here that the password is still demanded by the sentry at night. The Byward Tower archway leads to the Outer Ward. Ahead is Water Lane once ten feet lower than it is today. To the left is Mint Street. Here until 1810 stood the Royal Mint. Here too are the casemates where many of the Yeoman Warders live, and at one time there was a tavern with a golden chain as its sign on the site of No 1 Casemate.
