LT2021-2022 m. Valstybinė saugomų teritorijų tarnyba prie Aplinkos ministerijos vykdė Žagarės dvaro sodybos parko planinės ir erdvinės struktūros atkūrimą. Šio projekto įvairiuose įgyvendinimo etapuose žemės kasimo darbų metu buvo atliekami žvalgymai. Jie vykdyti naujai įrengiamų ir atnaujinamų takų vietose, apšvietimo kabelių, melioracijos vandentiekio trasų vietose ir atstatomos dvaro tvoros vietoje. Iš viso buvo žvalgytas 41 500 m2 plotas. Takų vietoje žemės kasimo darbai paprastai buvo vykdomi 20-40 cm gylyje, rečiau kasta iki 50-60 cm gylio. Elektrostrasų projektinis gylis siekė 50-60 cm, o vandentiekio trasų - 1,1-2,15 m [p. 178].
ENThe New Žagarė Manor (northern Lithuania, Joniškis district) is mentioned in historical sources from the beginning of the 16th century. In 1858, the manor was acquired by the Russian Count Dmitrij Naryškin. In the early 1860s, the Žagarė Manor house was built in the neoclassical style. It was surrounded by an English-style park, which was established in the mid-19th century. Between 2021 and 2022, a total area of 41,500 m2 was surveyed at the Žagarė Manor. These surveys confirmed the results of archaeological excavations carried out in previous years: that the grounds of the manor park contain only a 19th- and 20th-century archaeological layer, with some artefacts. During the survey, fragments of four buildings or engineering networks were located in the grounds of the manor house. A sewage sump dating from the late 19th to the early 20th centuries was unearthed adjacent to the left wing of the manor house. Fragments of another brick structure was found in the NE part of the manor grounds. The foundations may have belonged to a brick outhouse or a farmstead, built in the second half of the 19th century. The remains of the foundations of the third building, dating from the late 19th to the early 20th centuries, were probably those of an icehouse. The building was demolished or abandoned before 1948. Fragments of a fourth building were uncovered to the SE of the gardeners house. The foundations found were probably related to the outbuilding or farmstead marked on the 1921 area plan. They may have been part of a porch or terrace. The building was demolished at the end of the 19th or beginning of the 20th century.
