Simsbury Grew Where the River Broke Through the Mountain

Research conducted August 2026. Figures and website details reflect that date.

Simsbury sits in a valley with a wall on one side. Talcott Mountain runs the length of the town's eastern edge, and the Farmington River runs north along the ridge's west side until it finds a break in the rock at Tariffville Gorge and forces its way through [1]. That single geographic fact decided almost everything else. The river had nowhere else to go, so the one place it broke through the mountain became the one place in town with enough water power to run a factory.

Hopmeadow Street runs parallel to the river on the west bank. It has been the town's main road since English settlers began arriving from Windsor in the 1660s, and the town center grew up near an early ferry crossing back to Windsor [2]. A bronze plaque near Pent Road still marks where the ferry landed [2].

The town's oldest industry left the fastest mark. In 1836, Simsbury resident Richard Bacon partnered with an English firm to manufacture William Bickford's newly patented safety fuse, a woven cord that let miners light a blast and get clear before it went off [3]. After a fire in 1851, Joseph Toy moved the operation to the Hopmeadow Street site it still occupies, drawn there by the water power of Hop Brook [4]. On December 20, 1859, an explosion and fire killed eight young women who worked the fuse lines [1]. A brownstone monument in Simsbury Center Cemetery still marks the deaths. The company survived, passed by marriage into the Ensign and Ellsworth families, and became Ensign-Bickford, described in a 1995 federal survey of the town as "still the town's largest employer" [2]. That description no longer holds, and the reasons why run through most of this article.

Four miles northeast, the river's one useful break in the mountain built a second, harder story. In 1825 the Tariff Manufacturing Company raised a stone mill at Tariffville Gorge to weave wool into carpet, using immigrant labor and importing housing along with it [5]. The village grew to 2,000 people by 1852. That same year, the company's owner went bankrupt, partly from overexpansion, and the population fell to 600 within a season [5]. The mill reopened smaller, burned again in 1867, and was rebuilt as the brick pier building that still stands on the riverbank, having since passed through at least four owners in industries from silk to cutlery to screws [5]. Tariffville is the only mill village Simsbury ever had, and it never fully recovered from what happened to it in 1852 [5].

Tobacco filled some of the gap. Broadleaf shade tobacco became the last Tariffville-area business to employ a real number of workers, and it drew seasonal labor from well outside Connecticut. Martin Luther King Jr. worked a Tariffville-area tobacco field as a Morehouse College student in the summer of 1944 [1]. By the 1990s, a federal historic survey described the tobacco trade as finished, its former workers "employed elsewhere" [5].

Population tells the rest of the story. Simsbury had 2,737 residents in 1850. By 1900, after Tariffville's collapse and decades of farm abandonment, that number had fallen to 2,094 [6]. It then nearly doubled by 1950 and grew almost fivefold by 2000 [6]. Nearly everything a visitor photographs as Simsbury's built character today, its downtown, its neighborhoods, its schools, was built during that fifty-year suburban boom, wrapped around a historic core that federal preservation records date to between 1752 and 1933 [2].

The corporate-campus era came after that boom, and it is now leaving. The Hartford employed about 1,500 people at its Simsbury campus until it announced in 2013 that it would consolidate to Hartford and Windsor [7]. A developer bought the vacant 200 Hopmeadow Street site in 2016 and later tore down roughly 640,000 square feet of office space; housing proposals for the land are still moving through the town's zoning boards [8]. Chubb is completing a similar exit now. In June 2026 a developer bought the insurer's 82 Hopmeadow Street building as a condition of relocating Chubb to Windsor [9]. The town's own zoning code still carries the Hartford's name: the Hartford-Simsbury Form-Based Code governs what can be built on the land the insurer left behind [10].

What remains, by the numbers, is a town that mostly works somewhere else. Simsbury holds about 9,600 jobs and about 13,700 employed residents, with a mean commute of 25 minutes [11]. The five largest employment sectors are government, health care, insurance, restaurants, and grocery stores, not manufacturing [11]. Just 12 percent of the town's grand list is commercial or industrial property [11]. The six businesses in this article, an aerospace and defense manufacturer, a nonprofit senior living campus, a boarding school, a fuel-technology maker, a skating center, and a family-run saw blade shop, are what remain of a town that once ran on its own factories and now mostly houses people who work somewhere else.
