- Apadana — An architectural term designating a massive audience hall of hypostyle form (with the ceiling supported by rows of massive columns), characteristic of the royal palaces in Ancient Persia (especially those from the Achaemenid Empire period, such as in Persepolis and Susa). This monumental structure was used by monarchs for grand imperial receptions and public assemblies, being renowned for its complex decorative bas-reliefs.
- Apollodorus — The name of several illustrious figures from classical Antiquity, the most famous being Apollodorus of Damascus (2nd century AD), a renowned Syrian architect, engineer, and builder in the service of Emperor Trajan. He designed foundational monuments for the history of Dacia and Rome, including the bridge over the Danube at Drobeta, Trajan's Forum, and the famous Column, being considered a genius of monumental architecture.
- Arcosolium — An arched burial niche carved directly into the rock wall of early Christian catacombs or ancient tombs, located above a flat grave covered by a horizontal slab. In a structural-architectural sense, the arcosolium served both a decorative role, often acting as a surface for fresco paintings with allegorical Early Christian motifs, and a structural load-bearing role for the vault, typically reserved for high-ranking figures or martyrs.
- Pit-house — An archaic semi-subterranean dwelling, a rudimentary pit-house, or a partially buried underground room historically used on Romanian territories as a shelter, storage facility for provisions, or a dedicated workspace for installing a manual weaving loom. In a structural sense, argea represents a type of vernacular architecture excavated into the soil, featuring walls lined with timber or woven twigs and a low roof covered with reeds or sod, optimized for natural thermal insulation.
