Victor Frankenstein created two monsters in two different places. His first lab was a “cell” at the top of his house in Ingolstadt, Germany. His second lab was a miserable hut on one of the remotest islands of the Orkneys. Both of them were hidden and contained body parts and instruments for creating monsters.
Detailed answer:
Mary Shelley wrote Frankenstein. In this book, Victor Frankenstein, a young man obsessed with science, tries to experiment by creating life out of death. Since such an experiment looks like playing God, people are unlikely to approve of it. So, Frankenstein has to hide his work from others.
Victor chooses a chamber at the top of his house in Ingolstadt, Germany, to be his laboratory. The lab description appears in Chapter 4: “In a solitary chamber, or rather cell, at the top of the house, and separated from all the other apartments by a gallery and staircase, I kept my workshop of filthy creation.” In this room, he kept the materials, such as human body parts, necessary to make a creature.
It took Victor about two years to animate a dead body. When he managed to do so, he was frightened and left the house, and the creature managed to escape. Victor and the monster met again in the Alps. There the beast asked Frankenstein to make him a wife. Victor agreed and thought of a suitable place for the new creature.
During his trip to England, Victor continues his experiment on one of the Orkneys’ remotest islands. He rents one of the three miserable huts situated on the island. The place has two rooms, a roof that has fallen in, unplastered walls, and the door that is off its hinges. Victor has the door repaired, brings some furniture, and proceeds with his work. When he has almost finished his second creature, the first monster comes to him. Victor realizes what horrible consequences his experiment may have for humanity and destroys the second creature.
