Construction works carried out in September 2005 in the garden of a private villa in Morszyńska Street (Fig. 1), in Sadyba quarter in Czerniaków (in Warsaw’s southern district Mokotów), led to the uncovering of two cloche graves set close together. Both cloche vessels occurred at the depth of ca 120 cm from the present--day ground level, within clean yellow sand (Fig. 2). Both of them rested on a ‘stand’, ie a layer of several dozen heavily burnt sherds from different vessels (Figs. 3f.g, 4, 5), arranged tightly in a rectangle. The two burials were probably contemporaneous and may be viewed as a single deposit consisting of two graves. Under the cloches (Fig. 3a.d) were found urns with burnt human bone. The complete urn found in grave ‘A’ – with a broad body and smoothed neck (Fig. 3a) – was covered by a hemispherical bowl with a polished body (Fig. 3b), set upright over the mouth of the urn. The urn from grave ‘B’ – with a broad body and roughened surface and smoothed neck (Fig. 3e) – broke during construction and was dumped outside the grave. The rectangular ‘stand’ included fragments of a vase-like vessel with a tall neck (Fig. 3f), ornamented bowl with a short neck (Fig. 3g) and two large broad-bodied vessels with well-defined necks emphasised by notched cordons (Figs. 4, 5). The pottery from Morszyńska St. is typical for Cloche Grave Culture ceramic forms known from the region of Mazowsze (cf T. Węgrzynowicz 1988, p. 8–10, fig. 5); in ornamentation and technology it is also consistent in general with vessels known from Cloche Grave Culture sites recorded in the area. The only non-typical feature is the ornamentation of sherds from the bowl which were used to make the rectangular ‘stand’, and the notching of the lip of the bowl from grave ‘A’. Also worth noting is careful preparation of the mixture of clay and large amount of crushed rock temper used to roughen (by daubing) the cloches and urns. The urn from grave ‘A’ contained the remains of an adultus woman, slender and tall (approximately 160–164 cm), in good physical condition. Grave ‘B’ produced the remains of a mature woman (?). Degenerative changes observed on spinal bones of this individual suggest hard living and heavy labour. Bones collected in the area around the two graves included a fragment of a young roe deer tibia diaphysis.
