Dom Cechu Młynarzy (ENG: The Millers' Guild House) on the Radunia Canal was built in 1894 under the patronage of the Church of St. Catherine. This building was, in fact, originally built in 1831 on ul. Na Piaskach (formerly Am Sande in the Danzig period), the street which runs parallel to the Radunia Canal. This was deconstructed and subsequently reconstructed in its current location, around the back of The Great Mill. The Guild House is a fine example of the Prussian Façade style of architecture that is more prevalent in Gdańsk (especially the buildings on Granary Island) than in any other city in Poland. During the Russian siege of Gdańsk in 1945, the building was completely destroyed and the site remained in ruin until its restoration in 1997. Since 2021, it has been the home of the Arte Infinita art gallery.

From nearby Most Chlebowy (ENG: Bread Bridge), known locally as 'The Love Bridge', the view of the Millers' Guild House is often referred to as 'the view that never changes'. This timeless factor is what draws many young couples for an unbeatable romantic moment, snap a selfie and put another padlock on the bridge.
