A monumental structure in San Francisco's Marina District, originally built for the 1915 Panama–Pacific International Exposition to exhibit works of art. It is the only structure from the exposition still on its site, although it was completely rebuilt between 1964 and 1974. It was designed to evoke a crumbling ruin of ancient Rome and became one of the city's best-known landmarks. Its centrepiece is an open rotunda with a dome 49 metres high, bordered by a lagoon on one side and by colonnades separating it from a huge curved exhibition hall on the other. The dome and columns are reflected in the calm lagoon, where ducks and swans swim, and visitors stroll among the colonnades and gardens; many come to take photographs. Walking through the gardens and colonnades is free and always open. Early morning, when the lagoon is still, or evening, when the dome is lit, is best, and it pairs easily with the Crissy Field promenade facing the Golden Gate Bridge.
And dome.
And reflections.
Rows of columns.
