Jesmond Dene park, a protected wooded river valley on the banks of the Ouseburn with pretty waterfalls and a boating lake, was left to the city 120 years ago by industrialist William Armstrong , inventor of the hydraulic crane.  Today this green corner of the city boasts an abundance of wildlife (the park is a perfect habitat for kingfishers and red squirrels), a petting zoo, and an acclaimed seafood restaurant and Sunday market.
