To commemorate the heroic struggle, the Monument to the Defenders of Modlin from September 1939 was erected. The unveiling was performed by the commander of the 1939 Modlin defense, Brigadier General Wiktor Thommee, in the presence of numerous soldiers from his September campaign. The ceremony took place on September 29, 1957, the anniversary of the surrender of Modlin Fortress. The initiative to build the monument came from the command of the 15th Bomber Division, and its design was presented by Sergeant Ryszard Lasota, a non-commissioned officer of the Military Police. Two Soviet cannons were added to the monument. The motive was the Red Army's participation in the liberation of Modlin from Nazi occupation. The monument was erected on the site of a monument to Marshal Józef Piłsudski, unveiled in 1928, which was destroyed only in the early 1950s when the Marshal's bust and baton were removed from its pedestal. Until the unveiling of the next monument, this place was forgotten and neglected.

The Open-Air Museum of Forest Architecture – a small open-air museum (three farmsteads) in the village of Granica near Kampinos. It largely represents the vanished wooden folk architecture of the Kampinos Forest. It is part of a small section of the once planned Ethnographic Park. It is part of the Jadwiga and Roman Kobendz Educational and Museum Center, part of the Kampinos National Park. https://pl.wikipedia.org/wiki/Skansen_budownictwa_puszcza%C5%84skiego_w_Granicy https://kampn.gov.pl/osrodek-dydaktyczno-muzealny-w-granicy

A great place, an old settlement with a double moat for defense, and some nice piers. Worth a visit.

A convenient place from which you can see the ruins of a granary and parts of wrecks sticking out of the water.

A brick defensive wall with embrasures, either on the slope of a rampart or at its foot in a fortress ditch, used in fortifications primarily in the first half of the 19th century. The wall could contain embrasures for small arms. The purpose of the Carnot wall was to make it difficult for an enemy to cross the ditch. It was first used by the French military engineer General Lazare Nicolas Carnot in his 1772 drawing. Some bricks clearly bear the names of the brickworks where they were made.

A monument in the form of a plaque with text and an anchor commemorating the first port of the reborn Second Polish Navy. It was unveiled on June 21, 1997, at the initiative of members of the Maritime League Association and the residents of Nowy Dwór Mazowiecki. The monument is situated on the right bank of the Narew River, directly opposite the entrance to the former naval port located near the Lieutenant Feliks Pancer Bridge.

The cemetery is truly impressive.

Good route markings, misleading names, a crooked mountain is not a mountain you climb on a bike.
