Things to see in Minneapolis-St Paul

This city favourite combines science and entertainment, with plenty of hands-on and high-tech exhibits amid the outstanding collections of fossils and artefacts. The McKnight-3M Omnitheater shows state-of-the-art IMAX films on a 27m (90ft) diameter screen and there are also 3D laser shows.

The 100-year-old-plus facility is more than just a zoo, although there are interesting animal attractions like the seal show. With a frog pond and Japanese garden, the adjacent glassed-domed conservatory is charming. Como Town is a small amusement park for tots and right outside is a lovely covered carousel with hand-carved animals. The park itself is surrounded by a golf course, lake and walking paths.

Life in America's so-called 'Gilded Age' (the late 19th century) is on display in the former home of Great Northern Railway magnate James J Hill. The enormous stone Richardsonian Romanesque mansion, completed in 1891, measures 3,240 sq metres (36,000 sq ft) and is an ode to opulence, with crystal chandeliers, stained-glass windows, sky-lit art gallery, intricate wood carving and a huge pipe organ. It's best to reserve tours in advance.

The old Gold Medal Flour factory is now a unique museum. An entertaining Minneapolis in 19 Minutes Flat chronicles the area's history. It recalls the time when Minneapolis was the world's milling capital of the world. Visitors can board a renovated freight elevator, the Flour Tower, sit on its bleacher-like seats and move up and down the eight stories. With lights, sound, and commentary from actual mill workers, they learn about flour milling. On the eighth floor there is a sweeping view of the Mississippi and St. Anthony Falls.

One of the country's top contemporary art centres, the Walker Art Center has a revolving collection of paintings, drawings, prints and sculpture featuring works by Mark Rothko, Andy Warhol, Willem de Kooning and other leading artists. A building expansion that doubled the Walker's size was completed in 2005. The adjacent Minneapolis Sculpture Garden covers 4 hectares (11 acres) and is the largest urban sculpture garden in the USA.

Dedicated as a federal courthouse, in 1902, this ornate Victorian jewel, with its fairytale turrets and towers, was saved from demolition in the 1960s and is now used for art exhibitions and civic activities. Originally, the Landmark Center would have witnessed many criminal trials, as St Paul was notorious in the 1920s and 1930s as a safe haven for gangsters like Ma Barker, John Dillinger and George 'Machine Gun' Kelly. Interiors are extravagantly decorated with high ceilings, marble and mahogany details.

A fantastic snapshot of Minnesota history and culture. Minnesota's Greatest Generation includes a 1940s-war equipment factory, 1950s TVs, motel sign, soda fountain, 1954 Ford, movie house and famous Minnesotans like Judy Garland, Bob Dylan and Laura Ingalls Wilder (Little House on the Prairie). This Must Be Hell takes you into a C47 and recreates paratrooper experiences during the invasion of Normandy. The authentic 1880s immigrant house chronicles the fifty families who have occupied it, including Italian, Irish and Hmong.
