In Tolkmicko, the Warmian bishop Łukasz Watzenrode in April 1508 convened a meeting with representatives of the cities of Gdańsk, Elbląg and Toruń. As the personal secretary of the bishop, Nicolaus Copernicus probably participated in the meeting as well.
Tolmicko is one of the oldest cities in the region - city rights were granted to it in the last years of the 13th century. There are still fragments of the defensive walls with a tower (from the 14th century), a cemetery chapel and the church of St. James the Apostle (from the fifteenth century) are all from the Middle Ages. The nineteenth-century monument is the church: Our Lady of the Angels.
The Regional Museum operates in the town hall building with a permanent exhibition entitled "In the footsteps of the past." The exhibits presented on it were obtained during archaeological excavations carried out in the Elbląg Upland. From the town hall observation tower you can observe the panorama of the town, the upland and the Vistula Lagoon.
From the port of Tolkmicko you can go on a cruise for eg. to Krynica Morska on the Vistula Split. The town lies within the Elbląg Upland Landscape Park. The Green Velo East of Poland Cycling Trail runs through the town, where cycling enthusiasts can ride 395 km in the Warmian-Masurian Voivodeship and nearly 1600 km in four others.
