The construction of The Maine Mall, an indoor shopping center established in the suburb of South Portland, during the 1970s, economically depressed downtown Portland. The trend reversed when tourists and new businesses started revitalizing the old seaport, a part of which is known locally as the Old Port. Since the 1990s, the historically industrial Bayside neighborhood has seen rapid development, including attracting a Whole Foods and Trader Joes supermarkets, as well as Baxter Academy for Technology and Science, an increasingly popular charter school. Other rapidly developing neighborhoods include the India Street neighborhood near the Ocean Gateway and Munjoy Hill, where many modern condos have been built. The Maine College of Art has been a revitalizing force downtown, attracting students from around the country. The historic Porteous building on Congress Street was restored by the College. Portland is known as a very walkable city, offering many opportunities for walking tours that feature its maritime and architectural history.
