Boundary Post from 1545

Highlight • Monument

A very old border post of the former Principality. Next to it is a board with a historical description. Access via a beautiful forest path or via a footbridge over a river.

In the 16th century, on the forest-covered southern edge of Ducal Prussia, due to the intensification of settlement, it was necessary to precisely demarcate the border. There were several attempts to achieve this, with unsuccessful efforts made in 1529, 1532 and 1540. In 1545, Prince Albrecht of Prussia asked the Polish king and the Grand Duke of Lithuania, Sigismund Augustus, to appoint a border commission. By an act of March 19 this year, the Polish King consented to the commencement of work. In August 1545, the Prussian and Lithuanian commissions met near the present-day village of Bogusze, at the tripoint of the borders of Prussia, Lithuania and the Crown, marking the border between the countries. In memory of this meeting, a border post was erected with the coats of arms of Lithuania and Prussia and a commemorative inscription in Latin, authored by Jerzy Sabinus, rector of the University of Königsberg. In 1907, the coat of arms boards were moved to the Königsberg open-air museum and their copies were placed on a pole.
The pole is located on the left bank of the Ełk River, at the top of the riverside escarpment, deep in the forest. A forest alley leads to it from the main road. Made of brick, plastered, cuboid in shape with an almost square base (1.75 m x 1.80 m), with a high plinth at the base and a crowning, profiled cornice. The upper part has a triangular gable and a gable roof, covered with ceramic tiles.

Ostrykół Wooden Church

Highlight • Religious Site

The church was built on the site of an evangelical temple burned by the Tatars in 1656. Today's baroque appearance comes from the time of the reconstruction of the church, i.e. in 1667. This wooden temple, currently Roman Catholic, hides many interesting facts in its structure. Particularly valuable are the galleries built on both sides of the nave, the choir, twisted columns in the Baroque main altar, Corinthian capitals, the pulpit from 1690, the Baroque organ from 1799 and the 18th-century baptismal angel. There is also a plaque in the church from 1700 commemorating the beginning of the Evangelical faith in the area of the current Prostki commune. Another interesting feature is a candlestick with a deer's head.

Abandoned Loading Ramp of the Former Chemical Plant

Highlight • Structure

Remains of the warehouses of the former "Chemical Plant". A vast area in the forest intersected by asphalt and concrete paths. There are certainly more than a dozen km of them.
A nice section leading to the village and Dąbrowskie lake.

At the crossroads

Highlight • Trail

The intersection of forest roads is the eternal dilemma of where to go now. Driving from Dąbrowskie: straight to the forester's lodge, left through the forest to the Długosze-Prostki asphalt road, right to Żelazki or even further to Ełk.
