  Motivated by the recent experiments of Jamneala {\em et al.} [T. Jamnaela
{\em et al.}, Phys. Rev. Lett. {\bf 87}, 256804 (2001)], by combining {\em
ab-initio} and renormalization group methods, we study the strongly correlated
state of a Cr trimer deposited on gold. Internal orbital fluctuations of the
trimer lead to huge increase of $T_K$ compared to the single ion Kondo
temperature explaining the experimental observation of a zero-bias anomaly for
the trimers. The strongly correlated state seems to belong to a new, yet hardly
explored class of non--Fermi liquid fixed points.
