Bremgarten's medieval old town occupies a narrow peninsula in a tight bend of the Reuss, with the river on three sides and the city wall on the fourth. The layout is unchanged since the thirteenth century: two main streets — the Marktgasse and the Antonigasse — converge on the central market square, with arcaded burgher houses lining both sides.
The town is recognised as one of Switzerland's "Heritage Sites of National Importance" and is unusually free of modern intrusions. Look up: many of the gabled houses still carry their original painted facades, some recently restored back to the soft pinks, ochres, and ironwork of the eighteenth century. The Zeitturm (clock tower) at the upper end of Marktgasse is the surviving gate from the original town wall.
