An off the beaten track museum is the Florence Nightingale museum, situated at the back of St. Thomas hospital. It is a quite small museum and most is contained in one room. It will take you on a journey on both the life and times of the lady with the lamp, but it will also tell you about the evolution of nursing with a focus on the military side. Though not big the museum can definitely keep you there for an hour or so and on a rainy day you can sit through a classic movie or two about Florence. The ticket is valid all day so you can always come back if it starts raining!
