Established by current Archbishop of Kraków (and close advisor to JPII) Cardinal Stanisław Dziwisz to commemorate the legacy of every Pole’s favourite Pope, construction began on this ever-expanding and evolving complex in 2008, and no final completion date has been established. Located in Łagiewniki, within convenient walking distance of the Sanctuary of Divine Mercy, the ambitious ‘Have No Fear!’ John Paul II Centre (the official name of which refers to his famous words during his inauguration speech) is essentially a ‘city within the city’ for hosting conferences and accommodating pilgrims. Among the many facilities are a hotel and conference centre, rehabilitation centre, meditation park, Pilgrims’ House and cafe. The primary highlights for visitors are the Sanctuary of Blessed John Paul II - a chapel with relics of the former pope, including a vial of his blood (open 07:30 - 18:00, in summer 07:30 - 19:00, sanktuariumjp2.pl); the John Paul II Institute - where visitors will see a copy of the Shroud of Turin (open 09:00 - 17:00, free admission); the John Paul II Museum - which displays the personal belongings of the Pope and a rich collection of papal gifts recieved during his world travels (open 09:00 - 17:00; admission 10/6zł; guided tours in English 70zł; archimuzeum.pl); and the observation tower - from which you'll see panoramic views of the surrounding area (open from April until the end of October only, 4/2zł).
Getting there is a bit complicated. A cab will cost you about 20-30zł, or take tram 78 to the end of the line at 'Borek Fałęcki' and walk about 10mins. Alternatively, get off earlier at 'Łagiewniki 1t' and switch to bus 735, which takes you directly there. With either public transit option you'll need a 3.80zł single-journey ticket.
