This three looped Pillbox variant was sited at the harbour entrance at Lowestoft opposite a Pounder Emplacement. Another example of this design can be found 14 miles to the south with a group of ‘two looped square’ pattern pillboxes.
The ‘two looped square’ Pillbox (Type 26 Variant?) is commonly found along the North Suffolk coast. It has an outer wall length of 12 feet 6 inches
