caryfukA repeating geometric pattern, consisting of tiny, L-shaped protrusions, covers the entire surface of this specimen. Central inscriptions clearly identify its belonging to Almada's municipal services and specify its function in the sewage system, which is crucial for lidological typology.
Manhole covers in Lisbon
caryfukThe central emblem depicts a stylised boat with waves surrounded by a grid pattern, an iconic symbol of Lisbon. The inscriptions 'LISBOA' and 'AGUAS RESIDUAIS' clearly identify the geographical and functional context of this example. According to the analysis of the Institute of Lidology, this is a robust urban artefact of class D400, which effectively fulfils its role in the infrastructure.
caryfukA distinctive geometric pattern with repetitive elements dominates the surface of the circular cast-iron hatch, which is set into the cobbled path. Inscriptions and the year 2002 are visible on its edge, allowing us to date this example of urban infrastructure precisely. The Institute of Lidology would note that the corrosion patina gives this specimen appropriate historical depth without compromising its functional integrity.
caryfukA geometric pattern composed of repeating 'T' shaped elements dominates this circular hatch, which is set in a concrete ring surrounded by irregular stone pavers. The exhibit bears the distinct markings 'B 125' and 'EN 124', indicating its load classification and compliance with European standards, always a pleasing finding for the Institute of Lidology.
caryfukThe surface of this specimen features a robust grid of diamonds that provides considerable traction as well as aesthetic uniformity, which is crucial to the study of philology. Two distinctive inscription plaques, 'S.L.A.T.' and 'EYSSA-TESIS', suggest the specific identity and potential function of this infrastructural artefact, although their precise meaning remains a matter for further research. The surrounding paving of small pebbles testifies to its integration into the urban environment, where it patiently endures the daily burden.
caryfukThis example of a drainage grate, carefully studied by the Institute of Lidology, exhibits a robust but uncomplicated design with a series of parallel slats optimised for efficient surface water collection. The surrounding concrete and asphalt matrix is marked by numerous cracks and erosion, a silent testament to the relentless action of time and the elements, while providing valuable data on the dynamics of urban infrastructure. The small but significant inscription "S1" on one of the slats serves as a cryptic identifier, the full meaning of which is the subject of ongoing research.
