During the ten days of the yearly fiesta San Antonio, this city is draped in colors and culture as it celebrates a multinational heritage stretching back nearly 300 years. Actually, the same could be said of San Antonio during the other 355 days of the year, when a stroll along the Riverwalk-past the Alamo, Market Square, and La Villita-shows how a place so steeped in history feels very much like a city of the future. Indeed, San Antonio is poised to prosper even more from its longstanding status as America's cultural, social, and economic gateway to Mexico, Latin America, and beyond. That prosperity is reflected in the wonderful residences of the Hill Country, with architecture influenced both by the grandeur of Texas and the Spanish-flavored warmth of the Southwest.
