St Triduana’s Aisle is the hexagonal chamber built against the south-west corner of Restalrig’s parish church, raised for James III in the 1470s over a spring whose water was reckoned to cure eye trouble — St Triduana was said to have torn out her own eyes rather than be admired for them. It was the lower storey of a two-tier chapel; the upper floor is gone, but the rib vault below springs from a single central pier and the echo is startling. The church beside it, wrecked at the Reformation and rebuilt in 1836 on its medieval walls, still holds Sunday worship. Free, but by arrangement — ring the church first. Duddingston Kirk pairs well with it.
