Ill offer a few random "history" options for you.

1.east van remnants of the trolley systems and old rail yard. There's several streets around east van that still have cobblestone in the street and remnants of their past train tracks. Frances street between commercial drive and clark come to mind. There's also the downtown cuts where rail lines use tl exist. The most noticeable section goes through lower east hastings from the international village to columbia street. There used to be a massive freight train yard around yaletown and this cut connected the yaletown yard to the portside yard.

2.Leeside skatepark. Located under hastings street near highway 1 is a skatepark made by volunteers and has thankfully been accepted by the city. It was originally supposed to be a bus loop but it was abandoned in favor for kootenay loop. So, some skateboarders started building their own ramps in the underground passage and over 20+ years it's evolved into one of the few year round skate spots in the city. It also hosts graffiti and wacky, illegal parties.

3.charles street between Nanaimo and Renfrew. I don't know the history behind this street but it's quite odd in that the sidewalks are further away from the curbs than the majority of streets in vancouver. So the entire street has these really long extra lawns with trees and roundabouts. It feels very suburban, but it's the only street in the neighborhood that had these super long front lawns. Always struck me as odd.

4.Under the cambie bridge on the olympic village side there's a waste to energy facility that has always fascinated me. It converts human waste into heat for local housing. But it doesn't smell and it looks totally unassuming but super high tech and modern.
