A contribution for the Weekly Photo Challenge: Masterpiece. This Monopteron, located on Wiesbaden’s Neroberg, was designed by P. Hoffmann in 1851 who used forms of early Florentine renaissance. So it appears to echo an echo of Greek Antiquity. But still: I like this building’s elegance and its sense of lightness (especially on a bright day), an I am intrigued by the way its circles and arches seem to form a vortex in this picture.
