The home of the Augustinian Canons was a long stone building. The entrance was on the south wall with a screened passage. Beyond the right hand screen was the Chapel just as it is today and beyond the left hand screen was where the canons lived and travellers were received. It was a typical medieval hall with a dais at the far end and tables stretching the full length of the hall where the pilgrims and travellers slept.
Below the hall was an undercroft used possibly as a kitchen and storeroom. In the 13th century, the hospital community consisted of a prior, brethren and sisters.
For the next 300 years, St John’s carried out its function of providing hospitality for travellers and pilgrims coming to Lichfield. It forged links with the inhabitants of Lichfield, some of whom must have used the Chapel as a place of worship, just as today.
A chantry was endowed and a chaplain appointed. Endowments included acknowledgements to William de Juvenis in whose memory a red rose is placed on the Feast of the Nativity of St John Baptist.
