One of America’s grandest mansions when completed in 1788, the house at 52 Power Street was home first to John Brown, a businessman, patriot, politician, China Trade pioneer and slave trader who participated in the debates and practices that shaped the new nation and the world. However, this is more than an eighteenth century mansion. It was the home of John Brown’s daughters and their families; the winter residence of the elegant Gammell family during the second half of the nineteenth century; the formidable mansion of Providence utility, real estate and trolley mogul, Marsden Perry in the early twentieth century. Today this magnificent and elegant building serves as a place in which the public can learn about these men and women who helped to create Rhode Island’s capital city.
