When the vineyards of Ungstein, a suburb north of Bad Dürkheim, were modernized in 1981, a Roman wine estate was unearthed. Among the finds was an ancient Kelterhaus (pressing house). Although you can view the open-air ancient wine estate at any time, because it's basically alongside the road, you can see the winepress at work only during an annual wine festival that held in late June. To get here, look for signs to Villa Weilberg, to the left of the Wine Road (B-271).
