Hill Valley

"You can't even invent a way out of Hill Valley!"

- The Tenth Doctor

Hill Valley is where Doc Brown raps in in Doc Brown vs Doctor Who. It is also mentioned in one of The Doctor's verses. The exact part of the town is the courthouse/clock tower. The DeLeorean time machine appears in the background as well.

Information on the location
Hill Valley is the hometown of Marty McFly and Doc Brown, as well as the main location of the movies. The movies have also shown past, future and alternate versions of the town. One of the most known places in the town is Courthouse Square, with the main building being the courthouse/clock tower, which plays an important part in the first movie. The clock in the tower is struck by lightning in 1955, resulting in the clock standing still from then. The strike also generated the 1.21 gigawatts needed for the DeLorean to travel back to 1985.

Information on the DeLorean
The Delorean is a time machine built by Doc Brown out of a DeLorean DMC-12, and it becomes his most successful invention. It's a plutonium-powered car, and it needs 1.21 gigawatts of energy (either created by a nuclear reaction or a bolt of lightning), with 88 miles per hours of speed in order to time travel. In a later stadium, the DeLorean was also able to fly. It is destroyed at the end of the third movie, but re-built by Doc Brown in the form of a locomotive.
