Taxes are now an established aspect of our lives, but scattered across Britain’s countryside are reminders of their earliest days, when farmers were obliged to offer 10 percent of their produce to the church: these are tithe barns. In this episode, Joseph Rogers explains how we can spot a tithe barn, what they were built for and how they have survived to the present day. Joseph is the author of Tithe Barns and Britain’s Greatest Bridges.
