The old bastion is sleeping

The silhouettes of an old fortification on the seashore are visible under the moonlight.
A turret with a pointed roof and spire is visible. Behind the bastion, the surface of the sea reflects the moonlight, slightly illuminating the walls.
An opening in the front wall and part of a narrow alleyway illuminated by a ghostly light can be seen.
The once formidable structure is now quietly slumbering in the night, waiting in the morning for new aliens - crowds of tourists.
The painting is done in acrylic and oil on canvas. It can be hung on the wall without a frame.
Now, it is at the home of a private owner.
