LT2004 m. birželio mėnesį LII MTS ekspedicija vykdė žvalgomuosius archeologinius tyrimus Siesikų dvaro sodybos teritorijoje (Ukmergės r., vertybės numeris - G 257K), siekdama nustatyti dvaro R dalyje buvusio pylimo vietą, išsiaiškinti jo chronologiją ir supylimo struktūrą bei pylimo santykį su griova. Taip pat buvo tirtas kelias, vedantis į dvaro sodybą, - nustatomas XVII a. buvusio kelio aukštis (altitudė). Viso dvaro teritorijoje buvo ištirtos 5 bendro 44 m2 ploto perkasos. Be šių darbų, buvo žvalgoma Siesikų ežero S pakrantė, kur 2001 m. archeologai S. Sarcevičius ir G. Gendrėnas ariamame lauke aptiko XVII a. buitinės ir statybinės keramikos radimvietę. 2004 m. vizualiai ir metalo detektoriumi buvo žvalgomas neužsodintas ežero pakrantėje esantis lauko paviršius [p. 154].
ENIn 2004 the LII MTS performed archaeological investigation in the territory of the the Siesikai Manor site (Ukmergė district) and surveyed the northern bank of the lake. The research aimed to identify the location of the rampart which used to exist in the eastern part of the manor, to establish its chronology, structure, relationship with the ditch and to define the altitude of the 17th century road. 5 trenches were excavated in the territory of the manor covering the total area of 44 m2. The northern bank of the Siesikai Lake where household pottery and constructional ceramics of the 17th century had been found in 2001 was surveyed visually and using metal detector. At the hypothetic site of the rampart its shape was identified. It was established that the rampart and the adjacent ditch of the pond were formed simultaneously with the rampart. The eastern rampart and the adjacent pond were formed less precisely than the rampart in the western part of the manor. 22 finds were collected: a whetstone fragment, fragments of pot body and rims and fragments of a flat stove-tile datable to the 17th-18th century. At the location of the road to the manor at the depth of 1 m the primary surface of the road was discovered. The road was formed laying branches and bush-wood; over that hydro-isolation layer there were brickbats and remains of the pavement. On the eastern bank of the lake 18 finds attributable to the 17th-19th century were collected. This must have been a location of the 17th century manor.
