Narkūnai Hillfort, Maštaičiai and Narkūnai Hillfort with Outworks, Bailey, and Ancient Harbour, Maštaičiai Hillfort with Outworks and Bailey
The names Maštaičiai and Narkūnai identify one 8.5-hectare complex above the Nemunas
The hillfort stands in Maštaičiai village, Kiduliai eldership, on the edge of the upland above the left bank of the Nemunas between two unnamed stream gullies. The Cultural Heritage Register protects the nationally significant monument as Maštaičiai and Narkūnai Hillfort with Outworks, Bailey, and Ancient Harbour. Its code is 24752 and its registered area is 85,277 square metres. A further 251,715 square metres form the visual protection sub-zone.
Narkūnai is an alternative name for this same complex in Šakiai District. It must not be confused with the separate Narkūnai Hillfort near Utena. The principal hillfort at Maštaičiai has its own register code, 3261, and the other four components are also numbered individually, so one place name covers several distinct pieces of archaeological terrain.
The exact Google Maps listing, place ID ChIJdWs7BXij5kYRnPJRUSUYtzc, marks 55.0784987, 22.911352. These coordinates are classified as a representative point because the complex covers more than 8.5 hectares and the official sources checked identify neither a confirmed visitor entrance nor a car park. The pin should not be mistaken for a guaranteed trailhead.
The current register distinguishes two outworks and one bailey, while VLE describes three baileys
The register's structure is precise: hillfort 3261, first outwork 24753, second outwork 24754, bailey 24755, and ancient harbour 37210. These are the five components of one monument. The first four form a sequence of increasingly large enclosures divided by ditches, while the harbour lies below them in the Nemunas valley.
VLE calls the three outer enclosures the first, second, and third baileys. In the current register, the first two are designated outworks and only the 105 by 100 metre outer enclosure is called a bailey. This does not create three extra features or change the total number of components: it is a difference in terminology for two defensive enclosures.
On the ground, the sequence matters more than the label. Approaching from the broader upland towards the Nemunas means moving through the bailey, second outwork, and first outwork before reaching the main hillfort, with each component marked by a different enclosure, ditch, bank, or slope. Some outer surfaces are rough grassland in the official photographs, but deciduous trees and scrub conceal much of the earthwork.
A seven-metre ditch protects the 50-metre main enclosure, while the outer enclosures grow progressively larger
The main enclosure is trapezoidal, aligned north-east to south-west, and 50 metres long. It is about 45 metres wide at the south-western end and 25 metres at the opposite end. A bank up to 0.8 metres high and ten metres wide survives along the south-western edge, while a ditch as much as 30 metres wide and seven metres deep cuts the hillfort off from the continuing upland. The eastern slope rises about 25 metres and the northern slope above the Nemunas valley reaches 33 metres.
The irregular diamond-shaped enclosure of the first outwork measures approximately 80 by 75 metres. The second outwork has a 100 by 70 metre quadrangular enclosure and a southern bank standing up to three metres high and 15 metres wide, with an outer face of four to five metres. The bailey is almost square at 105 by 100 metres, and its southern, western, and eastern slopes rise as much as 15-20 metres in places.
The current register describes the cultural deposits of all four fortified components as unexcavated. It records masonry traces noticed in the main enclosure in 1960 and reports a spearhead found in the area in 1923 that was subsequently damaged by its finders and did not survive for analysis. These are documented reports, not results from a published excavation or laboratory study of a surviving artefact, so they cannot support a detailed reconstruction of the castle buildings.
The ancient harbour is a silted 70 by 20 metre excavation, not a working landing place
The fifth component is ancient harbour 37210 at the northern foot of the hillfort. The Cultural Heritage Register describes an almost north-south rectangular excavation made as an inlet and boat-standing basin, up to 70 metres long and 20 metres wide. Its cultural deposit is likewise recorded as unexcavated.
Banks made from the excavated earth line its western and eastern sides. They extend up to 70 metres, stand as much as two metres high, and spread 20-25 metres wide. A ditch 1-1.5 metres deep and up to five metres wide cuts through the western bank near its midpoint. The register records that the basin is partly collapsed, silted, and diminished, while deciduous trees and scrub cover its sides and banks.
Harbour therefore does not mean a modern quay, boat launch, or maintained route to the water. This is human-shaped archaeological relief whose form and position connect it with an earlier Nemunas waterway. Its scale strengthens the interpretation of Maštaičiai as an important castle site, but the harbour alone cannot prove which castle name in the chronicles belongs here.
New Bayerburg is a proposed identification, while Christmemel remains a separate hypothesis
The register locates the New Bayerburg built by the Teutonic Order around 1344 at this complex, while VLE uses the more cautious wording that it is believed to have stood here. The sources describe a six-day siege in 1380 by Lithuanians led by Kaributas. A truce followed as assistance approached from Prussia, and the castle was captured and burned in 1384.
This chronology is important, but the archaeological deposits remain unexcavated in the register. The identity of Maštaičiai and New Bayerburg has therefore not been conclusively demonstrated by excavation. Phrases such as proposed location, believed to be, or identified by some researchers are more accurate than presenting the chronicle's castle as an undisputed fact on this exact ground.
The Šakiai District Municipality overview also lists Maštaičiai among possible locations for Christmemel, separately associating that name with a siege in 1315 and destruction in 1328. The register additionally records a suggestion that a castle associated with a nobleman referred to as Masto may have stood here. New Bayerburg, Christmemel, and the Masto attribution cannot be merged into one chronology: they are different hypotheses about the site's historical identity.
Visit the wooded complex in daylight, and treat its perfect rating as a snapshot from only two votes
Official register photographs from 2013 and 2022 show densely wooded slopes and ditches around the main hillfort, forest tracks, rough grass across parts of the outer enclosures, and a narrow water-holding hollow at the harbour. Erosion, old ploughing, pits, trenches, and vehicle tracks have disturbed the relief. This is not a reconstructed castle park: protect the slopes, never drive across the enclosures, and do not dig within the archaeological site.
The register preserves stories about a sunken castle and princesses, gold hidden inside the hill, a girl transformed into a toad, and a tunnel running under the Nemunas to Skirsnemunė. Another tale calls a hollow in the ditch the place of the Seven Princesses. These belong to local folklore, not to archaeological proof of chambers, treasure, or a tunnel.
The register's visitor-information and opening-hours fields are blank, and the official sources checked publish no ticket office, admission price, gate, or fixed schedule. On the verification date, Google showed round-the-clock access and a 5.0 average from two reviews, but neither map hours nor such a small rating sample guarantees an attended or safe visitor site. Two votes are exceptionally volatile and a single new score could shift the average sharply. Arrive in daylight and dry weather, wear sturdy footwear, and follow current local signs when judging access and parking.
