Benedict will head to Italian villa immediately following papal retirement

Once he steps down on Thursday, Pope Benedict XVI will begin his retirement in the papal summer residence at Castel Gandolfo, a sumptuous villa outside Rome with ornamental gardens, breathtaking views and its own farm.

Benedict will spend around two months in the palace, which is perched high on a rocky outcrop above Italy's Lake Albano, before withdrawing to a monastery within the grounds of the Vatican.

One wing of the palace looks out onto the main square of Castel Gandolfo, a mediaeval town listed among Italy's most beautiful, and it is from a balcony there that Benedict will wave goodbye just before resigning on Thursday at 1900 GMT and retreating to a life of prayer out of the public eye.

Townspeople and those who have worked in the villa and grown to know Benedict over his eight-year papacy will gather holding torches and rosary beads in the square to pray for him.

The villa and gardens, owned by the Holy See since 1596, expanded over the centuries to include other properties and now sprawl over 55 hectares (135 acres).

Inside the grounds, there are views down to the lake or glimpses of the sea beyond gardens decorated with sculptures, and orchards of apricot, peach and olive trees, and greenhouses of ornamental flowers.

The residence has long been a favourite with popes hoping to escape the infernal heat of a Roman summer and, at 426 metres above sea level, the palace is a cool oasis.

"The pope, who usually visits at Easter, has brought his stay forward by a month," said Saverio Petrillo, director of the Pontifical Villas.

"The situation is routine in terms of logistics, but exceptional considering the circumstances," he said.

Benedict's resignation "took us by surprise, it was like a lightning bolt out of the blue," said the white-haired Petrillo, who said he understood the pope's decision to give up the papacy.

"Here the pope will find a family atmosphere. There are no great works of art, no huge rooms," he said as he showed off reception rooms decorated with simple wooden crosses, bibles on tables and photographs of Benedict smiling as he walks through the palace grounds.

Cypresses and sculptured hedges line secluded paths in the gardens, but Benedict does not often stroll among the blooming flowerbeds or fountains, Petrillo said.

"He is a reserved man of study who is not a huge fan of the great outdoors."

Benedict will be accompanied by two private secretaries and four lay women and is expected to spend most of his time in his private apartment, which has a view of the sea.

The pontiff said in 2011 that at Castel Gandolfo, "I find everything: a mountain, a lake, I even see the sea," a phrase immortalised in a plaque on the town hall opposite the palace.

It was pope Urban VIII who first decided in 1626 to establish the papal summer residence in Castel Gandolfo, which is 30 kilometres (19 miles) from Rome and is also home to the large telescope of the Vatican's Observatory.

Pope Alexander VII called in Baroque architect Gian Lorenzo Bernini to develop a new wing in 1659.

Centuries later, after several other villas had been incorporated into the land, Pope Pius XI opened a farm, where he kept animals which had been given to him as gifts -- including wild boar and gazelles.

It now houses cows, free-range hens, cockerels and pontifical bees.

Freshly laid eggs, milk, vegetables, fruit, honey and fat rounds of caciotta cheese from the farm are eaten by the pope at breakfast or end up in the kitchen of the papal household back in the Vatican, or on the shelves of the tiny state's supermarket.

Last year the environmentally-conscious Benedict was also given vines to plant at the villa to make a locally-produced wine for his dinner table, with no carbon footprint.
