Portofino is a fishing village on the Italian Riviera coastline, southeast of Genoa city. Pastel-colored houses, high-end boutiques and seafood restaurants fringe its Piazzetta, a small cobbled square overlooking the harbor, which is lined with super-yachts. A path leads from the Piazzetta to Castello Brown, a 16th-century fortress and museum with art exhibitions and panoramic views of the town and the Ligurian Sea. One of the most popular resort towns on the Italian Riviera, little Portofino has just over 500 permanent residents. But that all changes on summer days when the sun is shining and the yachting set drops anchor in the harbor to wander about.
