The Viscount's Walk

Private site not open to visitors.In Roman times, the temple of Jupiter Penninus stood on the site of the present-day church, giving rise to the name of the commune. The castle we know today is the 4th to be built on the same foundations. It was built in 1766 by Michel Louis Fréteau de Saint Just. The castle's existence is attested as far back as 1050 by a royal edict, preserved in the Bibliothèque nationale, which mentions Peny as the lord of the fief. It has Roman foundations. The castle has been listed as a Historic Monument since 1946.

The bell tower was built on the site of an ancient Gallo-Roman tower. A first sanctuary, dedicated to Saint Stephen, was built around the year 1000 on the site of the current church.Some remains of the 12th century can still be seen in the church (square pillars with bare carving). After having the village of Vaux demolished to build his château, Fouquet obtained permission to restore the church in the nearby village rather than rebuild the one in Vaux. The restoration was carried out under the direction of Louis Le Vau, architect of Vaux-le-Vicomte, in the 1660s. The Sommier family, who bought the Vaux-le-Vicomte estate in 1889, also took a great interest in the church: major work was carried out until the outbreak of the First World War.

Le pont et le gué, qui permettent de traverser le ru d'Ancœuil, desservait le Moulin de Pouilly. Au début du 20e siècle le propriétaire du Moulin était également le propriétaire des Folies-Bergères de Paris. Les danseuses parisiennes venaient s'y reposer.Un gué est un endroit où l'on peut traverser un cours d'eau à pied, à dos d'animal ou en véhicule, sans s'embourber ni être emporté par le courant.

Blandy is a medieval fortress last one left as well restaured in the Ile-de-France region.The first baronial residence was built in the thirteenth century, in the form of a simple manor with an irregular surrounding wall. Later that century, considerable fortification work was done, particularly the three towers which were added to the fortified entrance tower. A large residential building was built inside these fortifications. The fourteenth century saw considerable development of the château defences, with a moat and a new tower entrance boasting a spiked drawbridge. In the second half of this century Blandy became the model for fortified castles. The keep, 39 metres high, defended by two drawbridges, was built. The keep was altered by the addition of new towers and curtain walls. Between the fifteenth and seventeenth centuries, the fortress gradually lost its military purpose and became a residential castle. More domestic buildings were built. In the early eighteenth century, Maréchal Villars, the owner of Vaux-le-Vicomte, bought the lands and fortress of Blandy, which was pulled down and turned into a farm. Little by little, the fortress disappeared. Bought by the town council in 1883, the ruins of the fortress were classified as a historic monument the following year. From 1970 onwards, volunteer associations began work on restoring the château. In 1992, the Seine et Marne general council bought the fortress and undertook a vast restoration operation. A complete programme of works has enabled this superb fortress to be resuscitated and become one of the leading tourist attractions in the department. This dashing fortress represents one of the flagship tourist site of the district.
