A canal runs along the northern edge of the park and down south to the Thames. Designed by John Nash and opened in 1816, the Regent’s Canal was, like so many new waterways of the time period, quickly obsolete.
A few dedicated people cling to life on the canal. Mostly, though, its only use to modern Londoners is as a place for a peaceful morning jog.
And I think it serves that purpose just fine.
