Sunset and Moonset Radial Lines
Seven stone and bronze lines embedded in the lower West Observation Terrace radiate out from the building toward the western horizon. Each line points toward a notable sunset or moonset position on the horizon. Visitors can look at oval stone plaques embedded along each line for a description of the specific positions. Sun positions are the winter and summer solstices and the spring and fall equinoxes. Moon positions are major and minor northern and southern standstills.
