the sistine chapel ~ cappella sistina is not a church, it is a chapel in the apostolic palace, the official residence of the pope of the catholic church, in vatican city. it was built from 1473 to 1483.
many authors rate the sistine chapel as the most beautiful christian building in the world - not because of its architecture, rather because of the frescoes which cover all walls and the ceiling. the painters included botticelli, ghirlandaio, perugino, rosselli, and above all michelangelo who created the whole ceiling and the wall with the last judgment.
the frescoes at the walls contain paintings of temples, of the last supper, and of ordinary people. very passionate is the last judgment, including the hell.
the largest creation is the one on the ceiling (its content list is below)..
the most mentioned picture of the ceiling galleries is "the creation of adam".
the sistine chapel still serves for religious procedures - and it is also the place where the cardinals of the catholic church meet to elect a new pope!
this is the end of the vatican galleries. the core objective was to present the striking architecture and tremendous art assembly (rather than religious facets) to be seen there - - visiting the vatican is indeed a 'must'.
