Molnar City was a city on the planet Acamar III. One of its neighborhoods was named Mesrop Village. Until his Age of Majority, Volnoth lived with his parents in this city.
In 2366, this city was mentioned in the birth record of Volnoth, which was accessible to the crew of the USS Enterprise-D via the Acamarian planetary database (TNG: "The Vengeance Factor", okudagram)
For the remastered episode, Molnar City replaced Lornak City.
