Poland–Belarus barrier
On 25 January 2022, Poland began building a border wall on the border with Belarus to prevent illegal immigration. Poland has begun work on a new 5.5-meter-high border wall along the Belarusian border at a cost of 353 million euros (407m USD) aimed at blocking the passage of refugees after a border crisis in the region which began in 2021. It is expected to be completed in June 2022.
