One of the tiny moons was visible through the slitted windows.

Inside, therefore, it was a round room, with narrow slitted windows looking in three directions.

This was more like an enormous fortified house, with thick stone walls and high, slitted windows.

The wind siphoning through the slitted windows above made a sound almost like a spiral of music.

It was a dingy space with bare painted walls and two high, slitted windows letting in a poor amount of light.

I lowered my head onto the curved headrest and watched the bars of light from the slitted windows move across the walls.
