The moons of Alpha Centauri are some of the oldest colonies of mankind.  Every major nation has placed their stamp on those moons, and most minor ones.  Most of the colonies are domed of course.  That goes with the territory after all.  But there are some really big domes scattered around, and some towers that humble any Earth-built tower ever imagined.  I’m talking kilometers in height.  They are a sight to behold.
