Vasknarva (Russian: Сыренец, Syrenets; German: Neuschloss) is a village in Alutaguse Parish, Ida-Viru County in northeastern Estonia.

[1] The settlement is located on the northern shore of Lake Peipus, on the left bank of the Narva River headwaters forming the border with Russia.

The village arose in 14th century next to an Ordensburg of the Livonian Brothers, erected in 1349 on the northeastern border of their Terra Mariana territory.

Demolished by Pskov troops, a new castle (Low German: Nyslott; Estonian: Vastne-Narva) was built at the site from 1427 to 1442, which became the administrative centre of a Livonian Vogtei (Vasknarva foogtkond).

Occupied by Pontus De la Gardie in 1581 and rebuilt under Swedish rule, it remained a fort of great importance, commanding the mouth of the Narva River and the border with the Tsardom of Russia.
