The Historic City of Coimbra

We were told the city of Coimbra was built on steep hills. I thought, surely they could not be steeper than the hills of Porto, right?  Wrong.  The historic City of Coimbra (pronounced co-eem-bra) is all about the hills and they are definitely steeper than those of Porto, and the cobblestone streets are brutal.  By the time we boarded our return train my feet were screaming.  But, would I do it all again?  Absolutely.
