Dear Johnny're talking about a large amount (several tens or hundreds of thousands of euros) in notes d you money in the bank. Perhaps fearing the crisis had made the commitment at the beginning stages of crisis (as an acquaintance of mine) and you were at home. Normal is what you asked for their source, you have never heard of money laundering. If the amount of money is large and you have no source documents are not to be able to deposit in any bank around (regardless of whether acquired legally for years with your sweat, so I guess it is). Unless the amount is relatively small, few (counted on the fingers of one hand), tens of thousands of euros (without prejudice on my part for what they suggest), you can choose any bank with better rates on savings accounts and open accounts with amounts initially to 5,000 euros (think about such amounts need not be their source) and gradually to make statements about 1000-2000 euros.
