Saint Bartholomew's Church The old church, built on the same site as the new one, was the castle chapel and previously the seigneurial chapel. The first stone was solemnly blessed on March 19, 1868. It was consecrated in 1869. The church plan is the work of Mr. Ozanne, the departmental architect. Mr. Fraglon, a public works contractor in Villandraut, won the contract for 80,000 francs. The total cost, including furniture and the architect's fees, reached 100,000 francs (€15,244). The church of Poyanne could be considered at the time one of the most impeccable new churches in the diocese: for its size, the height of its vaults, the boldness of the arcades, the harmonious proportions, the unity of style, the regularity of the whole, and the harmony of the details. The church is built in the shape of a parallelogram and without transepts. Its nave consists of a vestibule, a central nave, two side aisles, and a choir with a polygonal chevet flanked on the right and left by a small square chapel. It measures 35m long, 19m wide, and 13m high. The 10m deep choir receives light from the chevet through three long lancet windows. The main nave connects with its side aisles through five large arches that provide as many bays, supported by eight isolated pilasters. The vault rests on real capitals. The gallery is in perfect taste. The porch is very simple, displaying its decoration only at the main door. The patron saint of the church of Poyanne is Saint Bartholomew.

The decree of the Convention of 3 Pluviose Year II (January 23, 1794) ordered the planting of a Liberty Tree in all communes, a symbol of the Revolution's success over the Ancien Régime and its privileges. These were most often Italian poplars, symbolizing Equality, the Latin word "populus" meaning both the people and the poplar. The day after the proclamation of the Second Republic on February 25, 1848, the municipal council planted the most suitable tree from the Mugron forest, as a token of support for the Republic. Four years later, with the advent of the Second Empire, following a circular from Prince President Louis Napoléon, the Liberty Tree was cut down. "Its wood could be usefully used to repair the rubbish dump located in the lower courtyard of the Town Hall." The current tree, a pedunculate oak, was planted in 1947 during an event bringing together the Municipal Council and the population, including school children.
