Architecturally the most important of the many striking features of the palace is the arrangement in the vestibule by which the supporting arches spring directly from the capitals of the large granite Corinthian columns.
The Palace, an enormous structure covering a city block (it had 1200 rooms and cost more than $3,000,000), known as the oldest and most famous hostelry of the city, and architecturally interesting, was completely destroyed by the fire, but has been replaced by a new building.
Eu has three buildings of importance - the beautiful Gothic church of St Laurent (12th and 13th centuries) of which the exterior of the choir with its three tiers of ornamented buttressing and the double arches between the pillars of the nave are architecturally notable; the chapel of the Jesuit college (built about 1625), in which are the tombs of Henry, third duke of Guise, and his wife, Katherine of Cleves; and the château.
Architecturally, everything is subordinated to a conformity with the style of the original portion; and its gilded dome is a conspicuous landmark.
The Roman Catholic cathedral of St John, the Janskerk, with its interior in a state of preservation rare in Holland, is one of the finest architecturally in the country.
