In the interior on the north, the Cappella del Corporale possesses a large silver shrine, resembling in form the cathedral façade, enriched with countless figures in relief and subjects in translucent coloured enamels - one of the most important specimens of early silversmith's work that yet exists in Italy.
The castle of the Hohenzollerns crowns a high rock above the river, and contains a collection of pictures, an exceptionally interesting museum (textiles, enamels, metal-work, &c.), an armoury and a library.
Not until the year 1620 do we find any evidence of the style for which Arita porcelain afterwards became famous, namely, decoration with vitrifiable enamels.
From that time forward the Arita factories turned out large quantities of porcelain profusely decorated with blue under the glaze and colored enamels over it.
There is evidence to show that the art of decoration with enamels over the glaze reached Kieto from Hizen in Awata.
