Construction seam
The line between two surfaces of a structure that can be seen on the masonry and that shows two different construction phases is referred to as a construction seam or construction joint. It can indicate a conversion or extension, long periods of construction stoppage, but also a change of plan within an otherwise continuous construction progress. These seams can run both vertically (for example with extensions) and horizontally (with structures and changes in height).
Construction seams are a particularly important aid for periodization and chronology on buildings of all epochs . For building research , they provide informative references to the respective building history , which often cannot be completely reconstructed from the documents. The differences can relate to the material, be of a stylistic or construction method nature, sometimes they only consist of deviations in terms of offset. Construction seams hidden under the plaster and only temporarily visible often come to the fore during restoration work or can be opened up during research work, for example by drilling.
