While the mayor was an active supporter of the temple, and the road sign into town proudly proclaims Pessina Cremonese to be “free from racial prejudices,” there was some opposition from local politicians with the Northern League, the political party most closely associated with anti-immigrant oratory in Italy. A small group of protesters from Forza Nuova, an extreme right party, demonstrated when the temple opened.

Manuel Gelmini, a Northern League lawmaker in Cremona’s provincial council who unsuccessfully tried to block the building of the temple, said his main concern was the Kirpan, the ceremonial sword carried by orthodox Sikh. “For us, it’s a weapon, and people shouldn’t be allowed to go around armed,” he said.

He also objected to the use of Punjabi as the lingua franca in the temple. “They live in Lombardy,” he said. “How can there be integration if we allow them to speak their own language in a public space?”

But tellingly, the Northern League has not campaigned openly against the Indian immigrants working as bergamini. “As long as they respect our laws, work legally and learn Italian, they are welcome in our country,” Mr. Gelmini said.

Dilbagh Singh arrived in Italy when he was 14, and now, 12 years later, he speaks with the distinctive accent of his adopted hometown, Nogara, near Mantua. He said his compatriots “come here to work, and want to live peacefully.” To this end, Mr. Singh runs a Web site on Sikhs in Italy so that “Italians can understand us.”

“We want people to know who we are,” he said.

Nearly 16,000 Indian immigrants are legally employed in agriculture in Italy, with the Lazio region becoming the newest pole of immigration, especially for seasonal workers. “You only have to travel 100 kilometers from Rome to discover a world most people don’t even know exists,” said Patrizia Santangelo, a filmmaker whose documentary about the Sikh community in the province of Latina, “Visit India,” is to have its premiere in October.

Ms. Santangelo’s documentary exposes some of the exploitation that many immigrant workers are subject to, regardless of their provenance.
