From Dwarf Fortress Wiki
Take note that the entire left column of the workshop is composed of impassable tiles, making it easy to accidentally trap dwarves inside the workshop after it is built.
 Common Uses
- Because of the ubiquity of ores and fuel, and thus metal, it is usually easier to make crossbows at a metalsmith's forge, as it does not require an otherwise useless workshop. However, moody dwarves will occasionally require a Bowyer's workshop, and will eventually go insane if one is not available.
- Use of a Crossbow also requires Bolts, which are made in a Craftsdwarf's workshop, and a Quiver, made in a Leather works.
