I go often...
I attended school near this shrine, and now my daughter does too. I go often, and always see something new! It's beautiful from an architectual standpoint. Amazing from the historical perspective. There is a Holocaust museum there as well as the beautiful ornate, yet homey and welcoming church. They have a small gift shop. I took my Jewish Sister in Law who has been to the Vatican, and she said it reminded her of that trip. So EVERYONE should go!
