Favorite UB/Wonder synergies?

[Archaelicos]

I was thinking that some Civs get UBs that work well with certain wonders - national or otherwise. For example, the Egyptian and Native American UB is automatic with Stonehenge.

What other wonders have great synergies with a UB?

 

[AfterShafter]

It's kind of a half-arsed synergy, but Hammam and the Hanging Gardens are nice together with Mehmed. Tremendous health, and happiness boosts in your cities, and together this wonder/UB really play to Mehmed's strenght - freaky growth.

Angkor Wat and Madrassa or Obelisk

Roman Forum, National Epic, Parthenon
Dutch Dike, Moai Statues, Ironworks
English Stock Exchange, Wall Street
Carthaginian Cothon, The Great Lighthouse, The Temple of Artemis
American Mall, Wall Street
Malinese Mint, Wall Street
Chinese Pavilion, Hermitage
Russian Research Institute, Oxford University
Korean Seowon, Oxford University
Japanese Shale Plant, Ironworks
Viking Trading Post, Heroic Epic, West Point, Pentagon

Of course there are other community buildings that can improve upon those combos like adding Barracks, Stable, Drydocks, etc,... in with the Viking's Trading Post / Heroic Epic / West Point / Pentagon combo and so on. Edit: I didn't include the Spanish Citadel, the Mongolian Ger, or the Celtic Dun seeing as these UB's go obsolete at one point.
