Concerning the Maiden Bower at Dunstable a local versifier embodies the local idea :—
Still Tatternhoe dames rehearse their tale,
On eve of winter’s day
About a chest hid in their knoll
When Romans went away.‘Tis at the bottom of that well
On Castle Hill, they say;
Of good old gold it was brimful,
And lies there to this day.
From ‘Notes and Queries’ for December 24 1910.
This isn't about Maiden Bower but Totternhoe Knolls, a medieval motte and bailey castle on at nearby Totternhoe, which had an earlier Roman fortification on the same site.
