New Sweden: the US's long-lost 'secret' colony

From Swedesboro, New Jersey to Swedesburg, Pennsylvania, echoes of New Sweden live on. Here's where else travellers can see glimpses of it:

• The New Sweden Centre – based in Wilmington, but offers free, guided appointments to sites associated with New Sweden across the Delaware Valley

• Gloria Dei (Old Swedes') Church – the oldest-surviving brick building in Philadelphia and the oldest church in Pennsylvania

• Lower Swedish Cabin – a 1640s log cabin in Drexel Hill, Pennsylvania open from April to October

• Trinity "Old Swedes" Church – in Swedesboro, this is the first Swedish church in New Jersey and is home to a 17th-Century Swedish cabin
