Hazards for international travelers are everywhere.
Painted signs on the pavement at busy intersections remind pedestrians to "Look right" or "Look left" before crossing.
You have to watch for cars taking a "left turn on red after stop", and be wary of yellow lights, which usually indicate that a red traffic signal is about to turn green, rather than a green light to red.
In London, horses and riders, and an occasional carriage, are common sights. Sadly, you rarely see equestrians in Portsmouth any more.
A major difference between the two cities is the age and size of the buildings. The oldest surviving building in Portsmouth is the Jackson House at 76 Northwest Street, built around 1664. The second oldest extant house is the 1680 Dennett House on Prospect Street. These are relative newcomers compared to the Tower of London's White Tower, constructed more than 900 years ago, around 1078.
