It is an old and large village area wise (Second oldest village in the commune after Brzozowa, with Gromnik placing third), forming a valley between two low mountain ranges. The precise description of these mountain ranges are the "Pogorze Ci??kowickie-Ro?nowskie" (Highlands of Ci??kowice-Ro?now)mountains, which forms a park of the same name. Nature abounds with many deer, fox, and a large variety of rare birds. A diversified mix of trees make up the forests with Birch often numerous, and there is Oak, Pine and much more.
Long ago, the Tatars, on their way to Tuchow (22 kilometers North-East of Siemiechow) during the Tatar invasion of the year 1241, murdered 7 monks ("siedem mnichow") among other people and from this was the origin of the name "Siedmichow", later changed to "Siemiechow". The village was officially established on September 29, 1326 by King W?adys?aw Lokietek "na surowym korzeniu" ("from fresh roots" or "from the ground up") under German law and equally began to form a parish on "dwoma ?anami ziemi" ("2 ?anow of land). In the village are two parish churches and public school. The first mention of the existence of a parish was in the year 1349. The school was established before the year 1596.
According to historian Jan D?ugosz (L. B., III, 216), the village of 'Szemychow' had a parish at an early time and belonged to the Abbey of Tyniec (near Krakow) by virtue of privilege of King Kazimierz Wielk in the year 1354, however, Jan Spytek of Melsztyn took away the monastery by force, shortly before the battle of Worsk?? in the year 1398, in which he then died "...and fair justice was served for what was taken, that which belonged to somebody else...". Later, in his second reference (II, 276) D?ugosz quietly mentions that Siemiechow belongs to the Abbey of Tyniec.
In the year 1581, in 'Sziemichow' (Pawin?ki, Ma?opolskie, 118) there was a 'so?tys' (village administrator) belonging to Siemiechow, who counted in the village: 1 wealthy farmer owning 25 '?anow' of land, 10 small farms without fields, 3 bailiffs who own cattle, 8 bailiffs without cattle, 4 craftsmen, and the village administrator who owns 1 1/2 '?ana' of land.
The village boundries are: to the West is Fa?ciszowa, to the East is Gromnik, to the South is Brzozowa, and to the North along a large beech forest is ?ubinka.
Located in the former province of Krakowskie, district Biecki, according to records of the treasury from the year 1770 it was noted that the village of Siemiechow in the province and 3 'folwark' (granges), during that time, was owned by '''Ignacy Krasi?ski''', and he paid an annual military tax of 1266 z?p. / 17 gr., and a winter military tax of 458 z?p. / 12 gr. Ignacy, the third son of Jan (castellan of Wizna, near ?omza), and Ewa Trojanowska, brother of Adam (a bishop), and Micha? Hieronim (great-grandfather of world famous Polish poet, Count '''Zygmunt Krasi?ski'''). In the year 1769, he received governorship of Siemiechow, in the district of Biecz, from his first wife, Maryanna Krasi?ska Jordanow (kancl. 40 f. 14). Due to the Office of Assessments court assessors, he resigned in the year 1788 (M. 301 f. 46). He became a bachelor (got divorced) from the order of St. Stanis?aw which he received in the year 1786. The heir of the Oblas of Radom, he got married for the second time in the year 1774 to Agnieszka Potka?ska, castellan of Radom, and had a daughter, Anna, who's first marriage was to Kazimierz Walicki, governor of Sochaczew, and second marriage to Miko?aj of Oplow Bronikowski, general major in the royal military, in which he wrote his life testimony in the year 1795 (DW. 110 f. 1299 i 111 f. 826). Amelia, one daughter of Bronikowski, got married to Count Roman Za?uski. During the period of the ruling Austrian government in the year 1772, the adminstration stole the entire estate from Kra?inski and then forced him to buy it back from them in the year 1789 at a very high price.
