Supposed it’s open only during a timeframe during Weihnachtsmarkts. It’s a tent, a big one with about a dozen to 20 vendors selling antiques of Stuttgart. If you’re looking for relics(antiques — antiquitäten) or just something unique and vintage. This is a nice place to come look for it. One might find a decade or century old table, sewing machine, flag, a book, toys, jewelry, paintings, vases, clothing or even pick up a souvenir from the older days of Stuttgart. If buying something is not your goal then one can always come here and just browse. The items sold by the vendors are worth a gander. The Café & Bistro inside is quite popular, has a nice setting and comfortable to dine in: for being set up inside a tent :] The staff is friendly and the coffee and punch is great!
