What: An intimate four-room spa-salon tucked into the Gothic cellars of Prague's Augustine monastery, reborn as an upscale resort from U.K. master hotelier Rocco Forte.
The look: A cool, minimalist whiteout with centuries-old arched plaster ceilings, old-world architecture, and a lunar-colony atmosphere.
Who goes: Central European nobles, local real estate moguls, and passing celebs like Pink and Tom Jones.
The treatment: Based on the dark lager originally brewed by resident monks, the St. Thomas is a 90-minute beer-based body rub followed by a full massage. Other treatments use natural products from Anika and Ila.
P.S.: Spa director Dita Coufalova may be diminutive in size, but she has the strongest hands in all Bohemia. (massages, $84-$317)
