Alhambra = 19
Apadana = 26 (25+1) not quite honest, because I like new wonders and Persia ;-) but more envoys can lead to quite some bonuses. OP on Prince and below, if you happen to have a good capital.
Big Ben = 30
Bolshoi Theatre = 12
Colosseum = 27
Colossus = 1
Cristo Redentor = 19
Eiffel Tower = 23
Estadio do Maracana = 2
Forbidden City = 28
Great Pyramids = 26
Great Zimbabwe = 24
Hagia Sophia = 14
Mausoleum at Halicarnassus = 22
Oracle = 7
Oxford University = 21
Petra = 7
Potala Palace = 21
Ruhr Valley = 21 (24-3) same as above, often not worth the building cost. Should not go that soon, but should not be in the top 5.
Terracotta Army = 14
Venetian Arsenal= 24
