Lost Barrio. 200 S. Park Ave.; Tucson. - This is an import district with 14 stores about a mile south of downtown Tucson. Some stores offer extraordinary wood and iron works by serious craftsmen. Some are European Import stores. We have purchased 3 beautifully carved doors for our home from La Casa Mexiana (formerly Aqui Esta), but the Lost Barrio stores have unique merchandise that will also appeal to visitors.
