Near the 11–12 locks of the Canal de Castilla, there once stood a paper mill
built in the 18th century and dismantled in 1983. Despite the scarce physical remains,
the absence of original plans, and the limited availability of data, this research aims to
reconstruct its initial layout, characteristics, and operation. To achieve this, an analytical–
synthetic method has been followed: in the analysis phase, multiple sources and materials
are thoroughly examined from various perspectives, while in the synthesis phase, drawing
is employed as a means of reflection, since any hypothesis about this factory must be
validated through sufficiently precise graphical representations. The most relevant result
is the complete drafting of the factory’s plans, including its machinery, as well as the
clarification of its production system. The main conclusion suggests that, although based
on the mechanisms and equipment of traditional paper mills, this manufacturing facility
sought to be innovative and exemplary in its time. Its dispersed typology was designed
to improve and dignify working conditions for employees, while its internal organization
optimized the paper production process and increased manufacturing capacity.
