Lancaster’s main attraction is its imposing castle, built in 1150. Later additions include the Well Tower, also known as the Witches’ Tower because it was where witches were held and accused during the famous Pendle Witches Trial of 1612. Immediately next to the castle is the priory church which was built in 1094 but renovated during the Middle Ages. Between the castle and the church are steps leading down to the 17th century Judges’ Lodgings, which was once the home to witch hunter Thomas Covell and now home of the Museum of Furnishings as well as a Museum of Childhood which has memorabilia from the turn of the 20th century. A few other museums worth checking out include: the Maritime Museum which explores the days when Lancaster was a flourishing port at the center of the slave trade; and the City Museum which has a variety of exhibits on local history and archeology. Lancaster’s highest point is the 22 hectare Williamson Park, from where there are amazing views of the town. On the park grounds is the Tropical Butterfly House, worth checking out for its array of stunning exotic species.
