Complex was formerly home to the Pontifical Belgian College where JPII resided during his studies in Rome.A magnificent 17th-century palazzo steps from the Quirinale Palace - Italy's seat of the presidency in central Rome - has come to market with an asking price of €30 million.  The complex, which includes a deconsecrated Baroque church, a private garden and 3,535 square metres of interior space spread across six levels, carries a history stretching back more than four centuries.     Among its most celebrated associations is the Pontifical Belgian College, which occupied the building from 1846 and counted among its former residents Karol Wojtyła, the future Pope Saint John Paul II.   Origins and history The palazzo's origins lie in the early 1600s, when the Discalced Carmelite friars established a convent and oratory on the site.   The Church of Sant'Anna - later rededicated to Saints Joachim and Anne - was completed in 1611 before being rebuilt in 1683.   Architectural historians have attributed the original design to Paolo Maruscelli, while Alessandro Sbreccio is credited with its subsequent execution, working in particular on the cupola.   The Carmelites sold the property in 1807 to the Sisters of the Perpetual Adoration of the Blessed Sacrament, from whom it passed to the Trinitarian friars in 1839, before being acquired and restored by the Belgian College in 1846. Property description The building's six levels - five floors above ground, plus attic and basement - accommodate 40 rooms and 15 bathrooms.   The ground floor retains its original vaulted ceilings largely intact, while the rooms on the first floor also with coffered ceilings and overlook Via del Quirinale.   The church, now deconsecrated, presents no independent façade to the street; instead, a grand portal opens directly onto Via del Quirinale within the face of the 18th-century building.   Inside, the interior is arranged on a Greek-cross plan inscribed within an octagon, formed by four great arches resting on gilded Corinthian pilasters, opening towards the two lateral altars, the apse and the entrance.   The garden - a rarity in this quarter of central Rome - extends to 614 square metres and is accessible from the ground-floor corridor via an internal courtyard. It has a lawn with lemon and orange trees and an outdoor dining area.   The property is being offered by Florentine luxury estate agency Lionard Luxury Real Estate at a guide price of €30 million.   Photo Lionard Luxury Real Estate
