The DC metro stations with this architecture (and several of the federal buildings downtown in a similar brutalist style) are some of my favorite places. Growing up in the area, the Metro was so exciting for field trips. It felt like being a grown up in a different underground world. The dramatic lighting, weird smell, and cave temperature of the underground ones feel so special to me. Built like a cathedral, stripped down to only the practical parts. Even commuting as an adult it feels special, those senses come back every time. I'm glad they have the same dirty hexagonal tiles at every station too!
