<p>An archaic hut built of ‘sticks and reeds’ was located on the S Palatine slope near the *Domus: Augustus and the *Scalae Caci by literary sources (Dion. Hal., <i>Ant. Rom.</i> 1.79.11; Varro., <i>Ling</i>. 5.54: <i>aedes Romuli</i>; Plut., <i>Rom.</i> 20.4; Dio Cass. 53.16.5; <i>Reg. Cats., Regio X</i>: <i>casam Romuli</i>; also associated with Remus by Prop. 4.1.9; perhaps linked to Faustulus by Solinus 1.18: <i>tugurium Faustuli</i>; Pensabene 117, 157; Balland 58-60, Coarelli). In antiquity, unusual care was taken to preserve the exact appearance of the archaic dwelling, which was maintained as a sacred site (Dion. Hal., <i>loc. cit.</i>).</p> <p>Archaeological investigations below the platform of the Temple of *Magna Mater revealed postholes in the bedrock belonging to three rather small, oval or rectangular Iron Age huts (<i>c</i>. 5 x 4 m: Puglisi 68, fig. 23; Davico 128, fig. 1; Angelelli and Falzone); these were probably quite similar in form to the Casa Romuli (Richardson; Pensabene 156). However, this area was covered over by the late-Republican period (s.v. Magna Mater, Aedes; Pensabene; as were the huts found below the <i>domus Flavia</i>: Tagliamonte 17), and thus Romulus’ hut, which Dionysius says ‘remained even to my day’ on the S slope of the Palatine (Dion. Hal., <i>loc. cit.</i>; in fact, the hut stood through the 4th c. A.D.: <i>Reg. Cats.</i>), must have stood elsewhere in the vicinity (Pensabene 157; contra, Castagnoli, who locates the hut quite far down the Palatine slope). Given the current evidence, the location of the Casa Romuli cannot be fixed (Balland 58) and thus can only be represented by an index number on our map.</p>
