| The upper level faces the Main Plaza. The four front doors all face precisely 118 degrees. The facade is unusual in that it is asymmetrical and may have originally been built that way. Between the doors, door-sized niches, now empty, create the impression of seven openings rather than four. Above the doors, the frieze has an upper and lower cornice. The ancient were faced with the problem of trying to create a symmetrical arrangement of frieze sculpture which would harmonize with the asymmetrically spaced entrances below. Over the three western entrances are three semi-quatrefoil shapes that form thrones for sculpture. |
