The Witness Wiki

For puzzle hints and solutions, see Glass Factory (Walkthrough).

The Glass Factory is a building on the cliffy beach just past the Entry Area. Unlocking the door and seeing the rows of vases inside should give you a good hint of what's to come – symmetry puzzles!

Most of the puzzles in the Glass Factory and the neighboring Symmetry Island feature a second line that mirrors the movement of the one you're drawing. The key here is to try to guide both lines through a successful path on the grid without hitting dead ends or bumping into each other.

If you follow the wire lit up by this last panel, you'll find it leads you along the cliffsides and up to Symmetry Island, where it has activated the first gate.

From the entrance to the Glass Factory, head up the path back towards the Entry Area and make a right onto the rocks that lead up to the roof of the place. Head down the stairs towards the water's edge and look below the stairs for the panel.
