The Lahun Pyramid is the funerary monument of Senusret II (also written Senwosret II), a king of Egypt’s 12th Dynasty. Built near the entrance to the Fayoum depression, the complex is famous for three things: (1) its mudbrick superstructure anchored on a limestone outcrop, (2) a hidden entrance on the south side designed to frustrate tomb‑robbers, and (3) the nearby planned settlement of Kahun, which produced the celebrated Lahun papyri and rich evidence for Middle Kingdom daily life.[1][2]
Unlike many Old Kingdom pyramids, the main entrance at Lahun is not emphasized on the north face. Excavators identified a southern entrance and passage system that leads to the burial chamber—one of several Middle Kingdom strategies for confusing intruders.[4]
The drawing highlights two “signature” features: the outcrop‑anchored core and the southern approach to the internal chambers. The real corridors are longer and more complex, but the concept is the same.[1]

el‑Lahun (Illahun), at the mouth of the Fayoum depression, south‑west of modern Fayoum (Al‑Fayyum Governorate).
Pharaoh Senusret II (Senwosret II), 12th Dynasty (Middle Kingdom).[1]
A mudbrick pyramid built around/over a limestone outcrop, once faced with fine limestone casing. Approx. 48.6 m high with a base around 106 m (values vary by measuring method).[7]
Famous for the hidden southern entrance, the planned town of Kahun, the Lahun papyri, and the nearby princess tomb treasures (e.g., jewelry).[2][5]

The Lahun Pyramid is the royal funerary complex of Senusret II, a major ruler of the Middle Kingdom’s 12th Dynasty. Unlike the classic limestone giants of the Old Kingdom, Lahun’s core is largely mudbrick, built over a natural limestone rise to save labor and stabilize the mass.[7]
In one sentence: Lahun is a Middle Kingdom royal pyramid complex where architecture, urban planning, and written archives intersect—making it one of Egypt’s richest “whole‑landscape” sites for history lovers.[2]
The pyramid’s visible ruin can look modest today because the fine outer casing is gone, exposing the mudbrick core. Yet the engineering concept is sophisticated: a core anchored on a limestone rise, with internal retaining walls and a controlled casing foundation trench to reduce the risk of collapse in rare desert rain events.[7]
Middle Kingdom architects increasingly experimented with non‑standard entry routes. At Lahun, the approach to the corridors is associated with the pyramid’s south side, while ritual focus (temple) remains conventionally on the east. This separation between ritual front and functional access is a hallmark of later pyramid security design.[4][7]
The wider Lahun landscape is famous for two types of evidence: elite burials linked to the royal house and the paper archives found around the town and temple areas.
Excavations in the area uncovered richly furnished burials associated with royal women, including spectacular jewelry caches often referred to as the Treasure of el‑Lahun.[5][6]
The settlement and pyramid complex produced one of the largest surviving groups of Middle Kingdom papyri, spanning administrative records, temple accounts, and everyday documentation—especially from the reigns after Senusret II.[2]
If you love “history you can touch,” Lahun is ideal: you can stand by the pyramid and then mentally “walk” into the adjacent town, comparing architecture, objects, and texts from the same landscape.[3]
Kahun is one of Egypt’s best‑known “pyramid towns”—a purpose‑built settlement tied to a royal funerary complex. Its housing blocks, streets, and neighborhoods make it a key reference point for Middle Kingdom urbanism.[3][4]
The Fayoum oasis region is a unique ecological and agricultural zone connected to the Nile by channels. Middle Kingdom kings invested heavily in the area; placing a royal pyramid at el‑Lahun signals how important the region was to state planning and prosperity.[4]
For modern visitors, this means you can combine Lahun with other Fayoum sites and landscapes—desert edges, fields, and lake‑region routes—within the same day.
Many objects from Lahun/Kahun—tools, personal items, and daily‑life objects—are featured in museum collections and research projects, helping you “extend” your visit beyond the site itself.[3]
el‑Lahun and Kahun became famous through late‑19th‑century excavation and publication. W. M. Flinders Petrie worked at the pyramid and the town, producing foundational plans and reports that scholars still consult.[4]
Modern work revisits Petrie’s plans with new methods (survey, materials analysis, and social/urban studies), and museum collections continue to publish and reinterpret objects and archives from the site. Digital Egypt and museum projects make many datasets accessible for study.[2][3]
Lahun is typically visited as part of a Fayoum day trip or multi‑site itinerary. Conditions and access can change, so treat practical notes as guidance and confirm locally when planning.[3]
Pro tip: pair your visit with a museum “follow‑up” (Petrie Museum / online collections) to see objects from Kahun and the treasure burials after walking the landscape.[3][6]
