The Koester House Museum, nestled in the heart of downtown, is an excellent place to take a look at life in Marysville before the turn of the century. Still luxuriously furnished with the Koester belongings, including family portraits, clothing, toys and books, furniture and household items, the house is a rare gem, completed in 1876, renovated carefully since the 1970s, and opened to the public through the generosity of the Koester heirs, who made it a gift to the city of Marysville.
