Museums:
The newly constructed Institute of Contemporary Arts (ICA) is housed in an impressive building, a work of art in and of itself, with the exhibition floor cantilevered over the Boston Harbor. The museum is free on Thursday nights with live music on a deck overlooking the water in the summer.
Boston's renowned Museum of Fine Arts (MFA) houses an impressive collection and inspiring temporary exhibits. Free admission for two can be picked up from the Boston Public Library, but some planning is required, since free tickets run out.
The Isabella Stewart Gardner Museum boasts a lovely and eclectic collection in a gorgeous mansion.
Landmarks:
The The New England Holocaust Memorial is between Government Center and the North End, on the Freedom Trail.
The John Hancock Tower in the Back Bay is Boston's tallest building, followed by the Federal Reserve Bank Building across from South Station.
Sites on the Freedom Trail that are worth a visit even if you don't walk the entire way include:
The Bunker Hill Bridge
The USS Constitution
The Old State House
The current State House
Every tourist visiting the North End inevitably stands in the long line for the famous Mike's Pastry on Hanover Street to try a cannoli. Truth be told, the lobster tails are more delicious! Another neighborhood staple is Bova's on the corner of Salem Street (parallel to Hanover and over one block) and Prince, open 24/7, but not the best bakery in town. The lovely smells wafting from the small shop two doors down on Prince will lead you to the true Italian delights.
