The Aldgate School, Primary school in City of London, England.

The Aldgate School is a primary school occupying a Grade II* listed building on Duke's Place, serving students from Foundation Stage through Year 6. The early 18th-century structure maintains small class sizes within its historic spaces.

Founded in 1709 by Sir John Cass, this school remains the only maintained school within City of London's administrative boundaries. This founding reflected early 18th-century efforts to provide education for local children.

The school community maintains strong ties to City of London traditions through shared ceremonies and local practices. These connections help students experience the neighborhood's customs as part of their daily school life.

The school occupies a historic building with limited space, so advance arrangements are recommended for any visits or tours. Access is via Duke's Place in the heart of City of London, which is easily reached by public transport.

In its early years, participants at Founders' Day celebrations wore red feathers to honor Sir John Cass. This distinctive custom, now less common, reflects the enduring connection between the school and its founder.
