Alvoco das Várzeas is a civil parish in the municipality of Oliveira do Hospital, Portugal, with 10.73 km2 and 320 inhabitants (2011).

The appearance of the millstones and mills and the legacy of anthroponyms that still exist today in Alvôco prove that this settlement was occupied by the Romans due, perhaps, to the vicinity of mineral holdings in meadows of Alvôco River.

Andrew, being a masterpiece of architecture in continuation of the regional tradition from the 19th century As a cause of greater interest in the parish, and obligatory visit, is its Medieval Bridge, although known by popular tradition as "Roman Bridge".

The main arc is a curve broken, gothic quarter, and of great openness; the other, smaller, trace is irregular but semicircular canal.

Along the bridge there is a fluvial beach and a picnic park, in the riverside area of Rio Alvôco (perhaps the least polluted water course of Europe).
