About

Ghent Audio Guide

Features
Read full description

Walk medieval Ghent in eight stops, from the old grain market to the counts' fortress. Hear why the city built a bell tower taller than its cathedral, how the van Eyck brothers' altarpiece survived looting, the Nazis and a still-unsolved 1934 theft, and why the prettiest quay in Flanders is really a receipt for the wool trade. Two narrators, real history, and a route you can walk at your own pace. Audio plays offline once downloaded.
