Historic Downtown Hastings, Minnesota

Early businesses in Hastings were located along the rail line. By 1908 the downtown was beginning to take on an aura of permanency, with brick buildings and important businesses such as a bank, hotel and general store.

These commercial buildings have been turned into fashionable clothing stores and cafes. Today, the Emerald clothing shop and the Miramax Cafe are two of beautifully preserved storefronts that attract hundreds of visitors daily.

In addition to great shopping and delicious food, the Hastings Theater, which has just re-opened after a major renovation project, is located here. The Museum of Photography will open this fall, bringing more of the arts to historic Hastings.

Call the Hastings Theater at (717) 334-6120 for information about show schedules and prices.
