Coliseum Center is a building under construction in Milan, Kingdom of Europa. It was proposed in 2007 by the city to surpass 65 Zagorska Street (Zagreb, Europa) which overtook UniCredit Building in 2006. Construction of this 2200 foot tower began in earnest, as they would also house the Provincial capitol. In June 2010 it overtook Trieste's Volta Building. But on July of that year the then-under-construction Euro 2 building surpassed it.
