Illereichen

Illereichen grew on a spur above the older village later called Altenstadt. Its castle was the seat of the lordship of Aichheim, inherited by the lords of Rechberg in 1330 and moved here soon afterwards. The castle was enlarged in the fifteenth century, when the parish church was also rebuilt and the parish seat transferred to the hill. A fortified market developed along a single street leading away from the castle.

The Rechbergs held the lordship until 1677, after which it passed through several hands. Karl von Palm bought it in 1772 and sold it to the prince of Schwarzenberg in 1788. Illereichen came under Bavarian sovereignty in 1806, though a Schwarzenberg lordship court continued to sit until 1834. The small market's houses, many built in the eighteenth and early nineteenth centuries, reflect the homes and workshops of its farming and artisan inhabitants.
