A logo for Ukrainian Greek Catholic Church, that is a Byzantine Rite Eastern Catholic Church, the second-largest particular church in the Catholic Church (after the Latin, or Roman Church). 

I was asked to combine their three main churches: St. George's Cathedral (Lviv, Ukraine), Patriarchal Cathedral of the Resurrection of Christ (Kyiv, Ukraine) and Santa Sofia Basilica a Via Boccea (Rome, Italy). That was kind a tough task because their appearance is so different.
