The LEGO® Arch 1 x 8 x 2 Raised (Part 16577) is a structural arch element designed to create wide curved openings in LEGO builds. Its raised profile and extended span make it useful for bridges, gateways, tunnels, and architectural detailing in castles, city layouts, and custom models.
Key Features
Raised arch design allows smooth curved openings across wider structures.
1 x 8 width provides greater span than smaller arch pieces.
Ideal for bridges, tunnels, and architectural builds where larger openings are required.
Compatible with standard LEGO® bricks and plates for stable integration into custom builds.
Building Ideas
This arch piece is commonly used for bridges, decorative gateways, and large windows in modular buildings. Builders also use it to form train tunnels, aqueduct-style structures, and layered architectural façades in castle and historical builds.
