L. Sonck, unrealised plan for Töölöö, Helsinki, 1898

This reproduction of Lars Sonck's second prize-winning entry for Töölöö appears on page 373 of Helen Porfyriou's 1990 thesis Scandinavian town planning from 1900 to 1930 and the contribution of Camillo Sitte. A less clear representation of the same plan which however covers more of its area appears on p. 130 of Lars Sonck: 1870-1956, architect published by the Museum of Finnish Architecture possibly in 1982 (the layout is very complicated). This is the part of the plan I'm interested in of course:

I gather Sonck was somewhat beholden to the ideas of Camillo Sitte, at least for a while, and he justified his plan on that basis. These two blocks clearly contain something within them, the left block probably has a church or some kind of statue, the right one seems to be just a dog-leg pathway with perhaps what was later called by Patrick Geddes a 'street room'. You'll see in the first picture there is something similar to the south of the left block.
