LVIV.MEDIA writes about memorial plaques (tablytsi). In October 2023 the executive committee of the city council approved a universal look for such plaques to fallen defenders, and the procedure for installing them, as reported by LVIV.MEDIA.
The publication says that the plaques go on the facades of schools and other educational institutions the fallen attended, and on residential buildings. The look was developed together with architects and is the same for all plaques.
What the publication does not give is the size and material of the sample. We do not guess them. If you need a plaque in Lviv, first ask the city council who makes them and to which sample.
A single look is useful beyond Lviv: several plaques on one wall read as one memory when size, material and lettering match.
