The ruined castle is Cetatea Trascaului, near Coltesti in Hungarian-speaking Transylvania (Romania).

The image that looks like something out of science fiction (below) was captured at the bottom of a deep salt mine near Turda, Romania. The theory is that salt impregnated air is good for respiratory illnesses. First excavated hundreds of year ago, a tourist complex complete with a ferris wheel, ping pong tables, and a lake one can row around has been built within the deep reaches of the mine to take advantage of the health effects—and to provide respite on a hot summer’s day.
