The Atlantic Tower is a large block arcology in Sector 13 of Mega-City One which featured in the 2012 film Dredd.
Role in Dredd
It is nearby to Peachtree Block, the head of Slo-Mo production throughout the city. Since it is in Sector 13 and named "Atlantic Tower" it is likely where New York City once was.
It is first seen when the corrupt judges are driving to Peach Trees.
