Villa Bethania, Historical residence in Rennes-le-Château, France.

Villa Bethania is a stone residence of light tan and pale ochre masonry in Rennes-le-Château, built 1901–1905 in a pseudo-Renaissance style. Its main facade rises to a gabled roofline capped by a square tower with a flat top and a small arched window; a lower wing extends to the right with a smaller square tower. A single round-arched window with a dark frame sits centered on the upper facade below the roofline.

Bérenger Saunière had the Villa Bethania built on land he bought in Rennes-le-Château, with the foundation stone laid on 3 June 1901 and work finished by May 1905. The architect was Tiburce Caminade of Limoux, the master builder Elie Bot of Luc-sur-Aude and the roofer Joseph Fabre of Dourgne. Saunière's account books show his estate, including the Tour Magdala, cost 26,417 francs between 1898 and 1905. He said at his ecclesiastical trial that the house was meant for retired priests.

The villa's interior holds a terracotta version of Murillo's Assumption of the Virgin, a figurine of the Infant Jesus of Prague, a painting of Thérèse of Lisieux and a painted copy of a tapestry by Alphonse Mucha. Stained glass with Sacred Heart symbolism sits below a Sacred Heart statue of Christ above the entrance. Saunière built a conservatory chapel beside the villa in 1910 to keep saying Mass after his suspension.

The museum entrance is on the villa's lower level, near the church. Entry is ticketed, and guided tours cost extra. The building has been owned by the municipality of Rennes-le-Château since 2000.

The house was later converted into a hotel, which drew visitors curious about the original owner's story. This transformation made it known beyond its original purpose as a private residence.
