Zelčín is a small village in the Mělník district on the left bank of Vltava.
The first historical mention of Zelčín comes from 1245 in connection with Queen Kunhuta and the knight Lambin. In the Middle Ages, fishing was the main duty of Zelčín. Since 1960, the territory of Zelčín has belonged to the municipality of Hořín.
Hořín is a village located about 2 km west of Mělník, and it was documented as early as 1319. However, it is certain that it was founded even earlier.
Orchards range from the lowlands to the foothills. The cutivated landscape with fruit orchards occurs mainly in the warm climate, but also significantly affects the slightly warm area. It is mostly an area of hills with undulating relief on the edges of valleys, lowlands and basins. On the route of the Elbe Trail, fruit growing is mainly represented by the villages of Daminěves, Lužec nad Vltavou and Cítov.
