Nestled along the picturesque French River in Thompson, Connecticut, the remnants of the Belding Corticelli Mill, dating back to 1862, stand as solemn witnesses to a bygone era. Located between the serene waters of the French River to the west and Riverside Drive to the east, the ruins evoke a sense of post-war desolation, with only three structures left to tell the tale of this once-thriving industrial complex.

This historic site is a quintessential example of 19th-century red brick industrial architecture and bears the distinction of being one of the earliest designs by the renowned Providence architects F.P. Sheldon and Son. Their innovative contributions, such as the high-pitched pyramid roof and the distinctive segmented arches adorning the grand stair tower, left an indelible mark on factories across southern New England during the late 1800s.

In its heyday, the Belding Corticelli Mill was celebrated for its production of silk thread, contributing to the textile industry's success. However, its journey eventually led to closure in 1962, marking the end of an era. Subsequently, in 2006, most of the complex fell to the ravages of time and demolition, leaving behind only the remnants that stand today.

The fate of the remaining structures hangs in the delicate balance of community input, environmental remediation, and the complexities of potential redevelopment. The future of these historic ruins remains uncertain, as they continue to silently narrate the story of industry and innovation in this quaint corner of Connecticut.

The mill complex itself, once a five-story brick giant measuring approximately 200 feet by 60 feet, was strategically situated several hundred yards downstream from the earlier Masonville complex. The near-flat roof, the gracefully curved segmentally arched lintels, and the commanding pyramidal-roofed central stair tower were architectural elements that set the standard for southern New England textile mills in the latter part of the 19th century.

Over the years, modifications have altered the mill's original form, with a steel and glass addition gracing its eastern facade. Nineteenth-century expansions include a four-story brick mill annexed to the west side and a one-story brick weave shed to the south. Associated housing, reflecting the mill's significance in the community, encompasses a frame boardinghouse and nine frame, double-entry dwellings.

Today, the Belding Corticelli Mill stands as a testament to the rich industrial heritage of the region, a reminder of the innovative spirit that once thrived within its walls. While the ruins themselves are off-limits, and trespassing is strictly prohibited, visitors can park on the roadside along Riverside Drive. From this vantage point, they can gaze upon the remnants of this historic mill complex, taking in the echoes of a time when industry reigned supreme in Thompson, Connecticut.
