Tum church is a fine example of early ecclesiastical architecture (circa 12th century) sitting among the fields of Mazovia, in the proverbial "middle of nowhere." It is one of the best examples of Romanesque architecture in Poland and worth a visit, especially if you are exploring the region.
From Warsaw, you can reach Tum Church by car by exiting from national route No. 1 onto road 703 (in the direction of Łowicz); in the village of Kwiatkówek, turn south. You can also get there by train or bus—to Łęczyca; it is a 2-km (about ½-hour) walk, or a short taxi ride away.
