Detinets

A detinets (Russian: детинец [dʲɪˈtʲinʲɪts]), dytynets (Ukrainian: дитинець [dɪˈtɪnɛtsʲ]) or detinetz (/ˈdɛtɪnɛts/ DET-in-ets) is an ancient Rus' city-fort or central fortified part of a city, similar to the meaning of kremlin or citadel.

The term was used in many regions of Kievan Rus', including Chernihiv, Novgorod, and Kyiv.

[1][2][3] Old Russian manuscripts mention detinets in various places of Kievan Rus' since the end of the 11th century.

[4] From the 13th to the 14th century, detinets were used only in the Russian Pskov-Novgorod region.

[6] Polish philologist Lucyjan Malinowski derives the similarly sounding Polish term dziedziniec–"courtyard", from detinets.
