Downtown LaPorte Historic District, Historic district in LaPorte, Indiana.

The Downtown LaPorte Historic District covers 70 contributing buildings in LaPorte's central business district, developed between about 1860 and 1930. Its earliest surviving commercial blocks, such as the Zahrt Blocks (1868 and 1874) and the Ridgway Hotel (1863), are two- and three-story brick Italianate structures with pressed metal cornices, tin window hoods and cast-iron storefront columns. The focal point is the LaPorte County Courthouse (1890–1894), a Richardsonian Romanesque design by Brentwood Tolan, surrounded by Queen Anne, Romanesque Revival and Neoclassical buildings.

The district grew between 1860 and 1930 as LaPorte expanded from a small settlement into an established town with growing commerce. This period of development led to the area being listed on the National Register of Historic Places in 1983.

Business names and construction dates are carved into several facades: the Lonn Block, Ridgway Block, Frederickson Building and Guggenheim-Weil Building all display them. The Zahrt Blocks at 607–609 Michigan Avenue were bought on speculation and resold to a developer, with tin brackets and window hoods on plain brick. Ground floors held shops, upper floors mixed offices and homes.

The district runs along Lincolnway and Michigan and Indiana Avenues, with the La Porte County Courthouse at 801 Lincolnway as the central landmark. Buildings line the streets in a compact grid, so a walk of a few blocks covers most of the 70 contributing structures. Look for the pressed metal cornices and window hoods on the upper floors, best seen by stepping back across the street.

The district sits at the crossing of two pre-European trails that once guided movement through this region. Its position on solid ground surrounded by lakes and wetlands made it a natural meeting point for trade and travel.
