Rose Plaza: Then
The photo above (click for a larger image) shows the Rose Plaza site as it looked 105 years ago. The building the "M" on the smokestack is the main refinery of the Mollenhauer Sugar Refining Company, and was located on Kent Avenue between Division Avenue and South 11th Street. The shorter building to the left on the river (technically on Wallabout Channel), a warehouse for the sugar refinery, was between South 10th and South 11th Streets.
The tall building beyond the warehouse is probably part of the Brooklyn Distilling Co., which once occupied the site where Schaefer Landing now sits. To the right of the Mollenhauer refinery is a building with a small tower and a mansard roof - that is one of the buildings of the former McLoughlin Brothers printing company. The building still stands on Wythe between Division and South 11th (it is now artists live/work lofts).
