Falmouth is the best-preserved Georgian town in Jamaica and has one of the most coherent ensembles of early nineteenth-century architecture in the Caribbean. The boom that built it came from sugar: in the early 1800s, Trelawny Parish was the richest sugar-producing area in Jamaica, and the profits flowed into handsome courthouses, churches, merchants' houses, and public buildings. The abolition of slavery in 1838 ended the boom abruptly, and Falmouth stopped growing. What had been built stayed standing.
The heritage walk covers the key buildings: Water Square (named for the hydraulic system that made Falmouth briefly the most modern town in the Americas), the Falmouth Courthouse (a beautifully proportioned Georgian structure from 1815), the Baptist Manse, Barrett House, and the Phoenix Foundry. A local guide from the Falmouth Heritage Renewal organisation can add the historical context that makes the buildings make sense. The walk takes one to two hours. On non-cruise days, you will often have the streets largely to yourself.
