The ancient water gardens below Sri Lanka’s Sigiriya Rock are as remarkable as the great rock fortress above them. Formal pools, fountains, channels and islands once formed a sophisticated royal landscape, while boulder gardens and terraces guided visitors toward a monumental lion-shaped gateway. Every part of the site rewards a different kind of vocabulary.
These 100 distinct terms cover the fifth-century capital, western water gardens, underground hydraulics, boulder and terraced gardens, frescoes and archaeological conservation. Each word has a clear definition, natural pairing and original Sigiriya-context example. The guide explains evidence and design principles without pretending every historic mechanism or lost building can be reconstructed with certainty.
The UNESCO World Heritage Centre inscribed the Ancient City of Sigiriya in 1982 and associates the royal capital with King Kashyapa I’s reign of 477–495 CE. The Sri Lanka Central Cultural Fund describes water, boulder and terraced gardens, alongside the Mirror Wall, paintings and summit palace remains. The Central Province tourism department details three formal water-garden sections, including two long pools, serpentine streams, underground conduits and a higher octagonal pool. Not every garden feature is unchanged since the fifth century, and fountains may operate only when water conditions allow.

92. Measured elevation — A scaled representation of the vertical face of a structure. Natural pairing: rock gallery measured elevation. Original example: A drawing can record height more precisely than a photograph.
93. Hydraulic schematic — A simplified diagram of connected water components. Natural pairing: Sigiriya hydraulic schematic. Original example: A schematic should distinguish documented channels from hypotheses.
94. Observation date — The day on which a specific feature or condition was recorded. Natural pairing: dated fountain observation. Original example: A fountain operating in one rainy season is not proof it operates all year.
95. Property boundary — The mapped limit of the formal World Heritage property. Natural pairing: Ancient City of Sigiriya boundary. Original example: The UNESCO inscription is not every nearby tourist attraction.
96. Archaeological context — The relationship of an object to nearby structures, deposits and chronology. Natural pairing: documented archaeological context. Original example: Context matters when interpreting lost structures.
97. Source attribution — Identification of the institution or researcher supporting a statement. Natural pairing: CCF source attribution. Original example: A source helps distinguish documented fountain design from guesses.

Four practical archaeology and garden exercises
Practice A: Label the three water gardens.
Using Sri Lanka’s official garden description, place the first water-surrounded plot, the second long pools and streams, and the higher octagonal pool in a simple schematic. State which details come from the source.
Practice B: Follow a plausible water system.
Name a water source, underground conduit, outlet and fountain. Explain the difference between a documented connected system and a hypothetical calculation of pressure without measured elevations.
Practice C: Distinguish art from chronology.
A fifth-century painting and a later visitor inscription are visible at the same site. Write sentences distinguishing an observed artistic feature, its proposed interpretation and the inscription’s independently supported dating range.
Practice D: Prevent conservation harm.
A historic fountain appears blocked and a fresco surface looks loose. Explain why heritage professionals must investigate both before any cleaning, testing or repairs are undertaken.

Describe one garden with more precision
Choose a credited view and identify the specific water-garden group, shape of one pond, its reported water connection and one associated rock or architectural feature. Attribute its history and separate an observable feature from a reconstruction. This is the best way to read royal landscape design as evidence.
