Exin Castillos: Double Arch Windows

Exin Castillos is a vintage Spanish construction toy with bricks measuring 12.35 mm wide.

This collection of double arch windows features pieces sized 1x1 with double and triple height, incorporating solid double arches that span them. The smallest piece, 1x1x2, is asymmetric, allowing it to be used in circular towers while slightly less protruding than a standard 1x1 brick.

These pieces are suitable for towers of any size, ranging from 3 to 11 NG and beyond, with varying dimensions to avoid repetition. They fit perfectly in octagonal towers formed by trapezoids.

When used in straight walls, the asymmetric side can create windows with a distinctive style. The 1x1x3 pieces feature decorative inner arches, enabling various archway designs.

Additionally, a 1x1x3 piece without an inner arch is available, although it may be more fragile due to the lack of reinforcement. The sills of all pieces align with the height and slope of traditional 1x1 inclined tiles.
