LEGO 75978 Diagon Alley

Released 2020 · 5,548 pieces · 17 minifigures · Harry Potter

LEGO Diagon Alley (75978) was released in 2020 as part of the Harry Potter theme, with 5,548 pieces and 17 minifigures. That makes it the 2nd largest of the 203 Harry Potter sets in the catalog. It was one of 10 Harry Potter sets released that year (see them all). Released in 2020, 6 years ago, well past the two-to-three-year run most LEGO sets get, so it is almost certainly out of production.
