As child we lived at the top of Ormesby Bank - One bedroom window looked across Middlesbrough transporter, North Ormesby, Cargo Fleet or into County Durham - often covered in smoke in those days. Another bedroom window looked across ICI Wilton it was like having Xmas lights every night of the year.
Ormesby Hall fascinates me, because of its long history, the saxon church, the surrounding woods (before the Parkway was built and that and my friends played in) how its land connected the mines and iron/steel making. the politics and interests of the family that lived there in the 1920s to 1960s. Its connections with the village that existed 150 years before Middlesbrough, but is part of Middlesbrough.
Some good suggestions on here, but Middlesbrough for me were places with the name in its address.
In central Middlesbrough - the Dorman Museum, Cenoteph and the gates and walls to Albert Park. As a child I stepped into a different world in that area - the park was an adventure playground with lakes, swans, fountains, skating rings, miniature steam railways, the museum took me to Africa, the walls of the park contained the names of some of my dead relatives, later as a teenager and young adult the Cenotaph meant Football, where I was dropped off and picked up from Boro games.
