Watchtower

"Where can we go?" "To the watchtower on the other side of the valley."

- Merlin and Finna

The Watchtower is a tower in the kingdom of Camelot. It has at least two floors connected by spiral staircases.

History
Merlin and Finna sought refuge in the watchtower after Merlin was injured by Saxons. However, Morgana and her men soon tracked them down, forcing them to retreat to the very top of the tower. With nowhere left to go, Finna sent Merlin to hide on the roof while she faced Morgana alone.

Finna ultimately committed suicide to prevent Morgana from finding out that Merlin was Emrys. Later, after Morgana and her men left, Merlin summoned Kilgharrah to carry him to safety (The Kindness of Strangers).

Trivia

 * The watchtower is likely located in the Darkling Woods, as that is where Merlin became separated from Finna (The Kindness of Strangers).
