Fun little thing I made. I calculated the Citadel’s heigh in reference to real world sizes. For reference, one mile is 3.6 cm, and the mini-Citadel is 10.44 cm, or the actual height: 2.9 miles, which is roughly 4.67 km. City 17 is a lot more densely populated in the Half-Life universe with those dark green parks on the map being filled in with buildings. I might post another image detailing Freeman’s journey through City 17 in HL2 and Ep1

that's not even counting what's underground. Ingames we don't ever see the bottom of the citadel and I hate that.
Yeah, and the fact that the architecture started getting different, like the Advisor chamber and Core, makes me wish we got to see the weirder stuff down there.
Wow! You've printed out the map!
Wow!
Is that an official map of City 17?
Half Life Alyx's map lines up nearly flawlessly with Sofia, Bulgaria. This is just a map of Sofia.
