The memorial stone at Udria Beach marks the landing site of the first wave of the Utria landing on 17 January 1919 during the Estonian War of Independence. From this shoreline, Estonian troops together with Finnish volunteers began the landing operation that contributed to the liberation of northeastern Estonia.

The first commemorative plaque was unveiled on 24 June 1939 on the initiative of the Udria Music Society. It was destroyed in 1940. After Estonia regained independence, the plaque was restored and reinstalled several times. The current version was ceremonially unveiled on 1 August 2015.
The third and fourth versions of the plaque bear the following inscription:

The Utria Landing took place on 17–19 January 1919 during the Estonian War of Independence (1918–1920). At the beginning of 1919, northeastern Estonia and the town of Narva were under the control of the Red Army. In order to change the military situation, Estonian command planned a naval landing operation aimed at attacking enemy forces from the rear and weakening their defensive positions near Narva.

The landing began on the morning of 17 January 1919 at Udria Beach. The operation involved Estonian military units, Finnish volunteers, and support from ships of the British Royal Navy. Despite harsh winter conditions, the troops secured a foothold on the coast and advanced inland. Narva was liberated on 19 January 1919. The Utria Landing is regarded as the largest amphibious operation of the War of Independence and one of the decisive turning points in Estonia’s struggle for independence.
