- The cartularies of ancient kings have designated Traînou with different spellings:
- Trianum
- Trianus (Latin)
- Triganou (around 1000)
- Triniou (1580)
- Traisnou (in 1649)
- Tresnoues (1671)
- Finally, in 1791, the National Assembly has officially sanctioned the spelling of the name, under that of Traînou.
- The etymology of the word Traînou:
- It is difficult to determine exactly the origin and meaning of the word Traînou. However, it is commonly believed that this word has been formed by the contraction of three and valleys (valley: small stream).
- What seems to give any reason for this etymology is that, indeed, the town is crossed by three rivers: the Crenolle, which begins in the village, crosses Donnery and empties into the canal of Orleans; Leash (or AISSE or Aisses River) and the border between Loury and Traînou and flows into the Bionne; trough ponds Puiseaux causes the waters to Cens, which it joins Fay-aux-Loges.
- The origins of the town:
- They may date back to Roman times, since the Roman pierrée lane direction Orleans, leaving the forest, passing the hamlet of Puiseaux and then branched off to go to Loury crossing the hamlet of Moreau motte (the root ball Mureau formerly.)
- Local tradition claims that in the Middle Ages, Traînou consisted of four towns: Clêchy, the current borough, Puiseaux and Gervaise.
- Archive we do not find mention of the church in 1021, when Clêchy, Traînou Loury and pass the territory of the Carthusians in the St. Croix chapter of Orleans.
- The hamlet of Clêchy:
- The hamlet of Clêchy is very old, since there was the church called in the ancient charters: capella, and cléchiaca tlépiaca. One finds traces, unless it were not those of a religious convent that served the chapel, in a former farm called the grand house, with visible air moat. This former farm is restored in recent years. Clêchy was one of three parishes data by King Raoul Anselm, Bishop of Orleans (923-930) for the maintenance of the Holy Cross canons. Hugh Capet and his son Robert mention of this chapel in their letters, speaking of Traînou (villa triganou pertinens ad clepiacam capellam).
- Chapel Clêchy was demolished during the religious wars and now Clêchy is only a hamlet.
- It is said that Joan of Arc would have slept in the farm more commonly called the "Grand'Maison" when moving between Patay and Saint Denis Hotel.
- The hamlet of Puiseaux:
- We know nothing of this particular hamlet, except that he was one of the three towns of Traînou and it is very old because the houses lining up the "paved road" old way Roman Sens in Orleans which was paved throughout its course and that one still finds in the forest of Orleans. You can discover this path or its edges, objects that attest to its age and importance.
- In the hamlet of Puiseaux once stood, a small lordship of that name, which belonged to the seventeenth century Sibois Refuge eral and later to FOYAL of Allonnes.
- The hamlet of Three Crosses and Gervaise:
- 1,5 km south of the town, on the road of Orleans, we encounter one of the most important hamlets of the commune.
- At its southern end, has established an ordeal of three crosses, this calvary built from time immemorial has probably given the name of "Three Crosses" in the hamlet. A peculiarity of this ordeal is that it occupies the northeast corner of a piece of land called "the gervaise". Or, Gervaise was precisely the capital of a provost of the chapter of Sainte Croix d'Orléans (a provost was a sort of court of first instance). Admittedly this was former provost since 1430, Jean Saint-Michel, Bishop of Orleans, recognized the jurisdiction of the nineteenth century, one could still see the remains of a small chapel called Chapel of Gervaise. The provost was abolished in the revolution and the county seat of justice of peace was transferred to Chécy.
- The present town and its church:
- The origins of the church dedicated to Saint Peter and Saint Fiacre would be between the tenth and eleventh century. This building is composed of a central nave pierced by three bays including two semicircular arched and third. In the eleventh century, the St. Peter chapel was built following the Saint-Fiacre chapel. In the twelfth century, the church became rectangular and was soon enlarged on the cruciform plan, the transept door indeed, right and left, two Romanesque arches. In the sixteenth century, a large square tower had to be completely taken over the Saint-Fiacre chapel but it was not completed. In the sixteenth century, the choir was redone with a flat patent and a magnificent Renaissance opening gives it the light of the rising sun. About 1876, important work the facade renovation took place. In the demolition, it was discovered a box containing bones of a lamb resting on the branches of boxwood (it is not known why this deposit to this place of honor.)
- In the choir of the church was buried May 23, 1684, Claude Lake, Esquire, Sieur de Montisambert and Traînou, also called lord of falconry; he was a descendant of Lancelot and the last Lord of Traînou which it is spoken in the records of the parish.
- The forest of Orleans:
- The wood of this forest that are part of the town for 855 ha and that line belonged until 1789, in part to Orleans and part of the chapter of the cathedral of Orleans. Those latter still bear the original wooden name of Holy Cross. During the revolution, these woods like the Duchy of Orleans were united to the domain of the state.
- Traînou The inhabitants number of residents who exercised in forest use rights and grazing. customary law: right of every needy of the town to remove the dead wood, heather and herbs. grazing rights: give power to all inhabitants to drive the cattle to pasture in the forest.
- Other more recent history points:
- The mill Traînou: This mill was first called the mill Trench Flûteaux then walnut and was established in 1827. Jules Cochin became owner in 1899. In 1935, there were 7 Traînou windmills. It was renovated and enlarged by Jules Arthur Cochin which awarded him a turret and a second pair of wheels. Later a motor came complete installation and an outer belt allowed to use discretion to grinding. The mill crushed wheat quinteaux about 940 per year. In 1941, faced with red tape the old mill, which the last miller, André Cochin, only then possessed more than 2 wings, fell. The mill Cochin was the last to disappear Traînou and was one of the last of the Loiret to operate with a traction engine.
- The crash of the B-24: During World War from 1939 to 1945, an American aircraft (bomber B-24 D Liberator) named Los Angeles City Limits Traînou crashed in the forest. Today, a monument was erected on the D124 road to Sully-la-Chapelle, in homage to the dead and the events they extend.
- Pond Traînou: It was dug in the 80's is located on the Roman road from Sens Orleans and adjoins the fountain of St. Peter which was a place of sacrifice. Today, it houses a fitness trail, orienteering is a fishing, relaxation and place of favorite promenade Trianiens.
- The pylon TDF (broadcast France): The town is recognizable pylon TDF 199 m high, mounted since 1968, which broadcasts radio, TV and DTT (Digital Terrestrial Television) specific to the channel 63, on entire Loiret, Eure-et-Loir and part of the Loir-et-Cher. This site serves 550,000 inhabitants. The pylon is also used to measure the greenhouse gas of Orléans. The new station of Ramces observatory completes airborne measurements above the forest of Orleans for 10 years. sampling lines go down three levels and used to sample air masses in the vertical. A specific line must be fitted to measure the radon gas. The station is fully automated and controlled remotely. It runs continuously from the beginning of 2007.
