Starting out today at our hotel, the City Hotel Derry, conveniently located in the historic area.

Near the Guildhouse, the Tower Museum and the Magazine Gate to the City Walls. We were met by a local guide here to walk us along the City Walls.

The Magazine Gate.

Derry is the only completely walled city in Ireland. The 1-mile (1.6 k) in circumference walls were built in 1613-1619 and they have never been breached. The walls are between 12 and 35 feet tall (3.7 and 10.7 m).

Walking along the walls.

These served as barracks for the British.

According to my bus driver, the political murals on the Protestant east bank of the river have been mainly painted over with new murals. We did ride past this mural of Willaim McFadzean, winner of the Victorian Cross.

Also, we viewed this mural of the Peace Bridge, showing both sides of the River Foyle.
