The explosion yesterday in Manchester, England, occurred at an entrance to Manchester Arena, one of the largest entertainment complexes in Europe, which is connected to the Victoria Station, a busy rail and tram stop near the center of the city.
The below maps show the neighborhood where Manchester Arena is located. It is near the city center, close to several parking lots, a soccer museum and a hotel.

The area where the blast detonated is between Victoria Station and Manchester Arena. The area is public and not close to security checkpoints for the venue. The detonation took place just as the concert was ending, as the area would have become a choke point for both commuters in transit and people leaving the show.
