The Eichstätter Garten or Hortus Eystettensis ("Eichstätt Garden"), also known as the Bastionsgarten (Bastion garden) was a botanical garden that was created during the Renaissance period under Prince-Bishop Johann Konrad von Gemmingen on the bastions of the Willibaldsburg in Eichstätt, Upper Bavaria. The plants in the garden were described in the magnificent botanical work Hortus Eystettensis, which was first published in 1613 on behalf of the Prince-Bishop. From Wikipedia
