Dome

Pyramid of the Mood, detail depicting stairs; The Pyramid of the Moon, which was completed somewhat later [than 150 CE], is smaller but no less impressive, by virtue of the precinct (framed by ten lesser stepped pyramids) within which it stands at the north end of the city's north-south axis, known as the Street of the Dead.
