Charlie Dobson took 400m silver to gain his first major individual medal at the European Athletics Championships, as team-mate Molly Caudery won pole vault bronze in Rome.
Dobson, 24, clocked a blistering 44.38 seconds to set a personal best in the final.
But that was not enough to deny Belgium’s Alexander Doom, who triumphed in a championship record 44.15secs.
Gold medal favourite Caudery, crowned world indoor champion in March, could not improve on a second-time clearance at 4.73m, as Switzerland’s Angelica Moser took a surprise victory as the only athlete over 4.78m.
Those medals took Great Britain’s tally to nine following golds for Dina Asher-Smith and the women’s half marathon team on Sunday.
Elsewhere during Monday’s evening session, Laviai Nielsen ran a personal best 50.71secs to finish sixth in the women’s 400m final, in which Ireland’s Rhasidat Adeleke (49.07secs) took silver behind Poland’s Natalia Kaczmarek (48.98secs).
Anna Purchase recorded a best throw of 69.24m to finish eighth in the women’s hammer final, as Sara Fantini won table-topping hosts Italy’s eighth gold.
Mark Pearce placed 13th with a time of eight minutes 26.92 seconds in the men’s 3,000m steeplechase final, won by Frenchman Alexis Miellet (8:14.01).
Daryll Neita cruised to victory in her women’s 200m semi-final, effortlessly confirming her place in Tuesday night’s medal race in a time of 22.51secs.
The men’s 200m final was won by Swiss athlete Timothe Mumenthaler in 20.28secs.
